In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Inhibitive properties, adsorption and a theoretical study of 3,5-bis(n-pyridyl)-4-amino-1,2,4-triazoles as corrosion inhibitors for mild steel in perchloric acid, published in 2008-02-29, which mentions a compound: 1671-88-1, mainly applied to mild steel corrosion inhibitors triazoles adsorption perchloric acid, Recommanded Product: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine.

Corrosion inhibition of mild steel in molar perchloric acid by 3,5-bis(n-pyridyl)-4-amino-1,2,4-triazoles (n-PAT, n = 2, 3 and 4) was studied at 30 °C using gravimetric and electrochem. impedance spectroscopy techniques. Protection efficiencies of 95% and 92% were obtained with 12 × 10-4 M of 3-PAT and 4-PAT, resp.; while 2-PAT reached only 65%. The inhibiting properties of n-PAT were found to depend on the concentration and the order of increasing inhibition efficiency was correlated with the modification of the position of the nitrogen atom in the pyridinium substituent. It was shown that adsorption of 4-aminotriazole derivatives on the steel surface is consistent with the Langmuir adsorption isotherm and the obtained standard free energy of adsorption ( Δ G ads 0 ) values indicate that the corrosion inhibition of the mild steel in 1 M HClO4 is depends on both physic-and chemisorption. A significant correlation is obtained between inhibition efficiency and quantum chem. parameters using semi-empirical quant. structure-activity relationships (QSAR) approach.

One of the two dicyanamide ligands is a terminal ligand, but the other one acts as a μ1,5-bridging ligand between pairs of CuII centers, so generating a one-dimensional coordination polymer. A combination of N-H···N and C-H···N hydrogen bonds, augmented by π-π stacking interactions, links the coordination polymer chains into a bilayer structure. Comparisons are made with some related CuII complexes containing dca ligands and heteroaromatic co-ligands.

Author is Bentiss, F.; Traisnel, M.; Vezin, H.; Lagrenee, M..

A quantum chem. study of the corrosion inhibition efficiency of triazole and oxadiazole derivatives, at the mild steel electrode, in molar hydrochloric acid (1M HCl) was carried out. The correlation between the mol. structure and inhibition efficiency of these heterocyclic compounds was investigated using a linear model encompassing the charge transfer resistance (Rt). The linear resistance model (LR) was optimized with the semiempirical quant. structure activity relationships (QSAR) approach. Regression equations, with multiple correlation coefficients superior at 0.90, were derived between 1/Rt and mol. descriptors. These significant correlations indicated that the variation of the corrosion inhibition with the structure of the inhibitors may be explained in terms of electronic properties.

As far as I know, this compound(1671-88-1)SDS of cas: 1671-88-1 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

Eight mononuclear nickel(II) complexes of the ligands 4-amino-3,5-di(2-pyridyl)-1,2,4-triazole (adpt) and 4-pyrrolyl-3,5-di(2-pyridyl)-1,2,4-triazole (pldpt) with the anions ClO4-, BF4-, PF6- and SbF6- have been prepared In all cases the metal/ligand ratio is 1:3, and the complexes are of the form [NiL3](A)2·solvents where L = adpt or pldpt and A = one of the aforementioned anions. Five of these complexes have been structurally characterized by x-ray crystallog.: four of these contain pldpt and strong anion-π interactions are observed, with two motifs present in all four structures. One of the anions occupies a “”π-pocket”” formed by two coordinated triazole rings and one coordinated pyridine ring. The other anion only interacts with one triazole ring, which is involved in the pocket around the first anion, such that the triazole ring is “”sandwiched”” by two anions. Surprisingly, in all four of these complexes, the two triazole centroid···anion distances in the anion-triazole-anion interactions [2.917(7)-3.005(10) Å] are significantly shorter than in any of the other types of triazole-anion interactions [3.164(5)-3.456(9) Å].

COA of Formula: C12H10N6. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms.

Variable-temperature magnetic susceptibility (7-460 K) and 57Fe Moessbauer spectroscopy data give evidence for a complete S = 2 (high-spin) ↔ S = 0 (low-spin) transition, taking place gradually, without hysteresis. The x-ray structure was determined at 298 K and 100 K. The compound is triclinic, space group P1̅, with a 9.277(2), b 9.876(3), c 12.272(2) Å, α 69.52(2), β 86.92(2), and γ 81.73(2)° at 298 K and a 9.236(2), b 9.684(1), c 12.137(2) Å, α 69.26(1), β 87.53(2), and γ 82.38(1)° at 100 K with Z = 1. Two abpt ligands coordinating via pyridyl-N1A and triazole-N1 are in the equatorial positions. Fe-N1 and Fe-N1A distances are 2.08(1) and 2.12(1) Å for 1 and 2.00(2) and 2.02(1) Å for 2, resp. TCNQ mols. coordinate axially at remarkably short distances i.e., Fe-N1T = 2.16(1) Å for 1 and 1.93(1) Å for 2. The TCNQ mols. are stacked in pairs yielding diamagnetic entities. The FTIR spectra (100-300 K) show that the TCNQ νCN vibrations are a fingerprint for the different spin states. In the isostructural [MII(abpt)2(TCNQ)2] (M = Mn, Fe, Co, Ni, Cu, Zn) compounds, the νCN absorptions show a shift to higher frequencies as a function of the crystal field stabilization energy. Above Tc, the Cu(II)-doped Fe(II) species shows a broad signal with g⊥ = 2.09 and g‖ = 2.25 and hyperfine structure (A‖ = 180 G). At Tc and below, the spectrum becomes better resolved and now shows superhyperfine structure (AN‖ = 16 G; nine lines). Above Tc, the Mn(II)-doped Fe(II) compound shows a very broad signal at g = 2.00. The spectrum sharpens at Tc to give a clearly resolved spectrum corresponding to a magnetically isolated Mn(II) ion in a tetragonal environment. The signal is split by the zero-field splitting, yielding major signals at g = 1.6 and g = 5.5 and six hyperfine lines (A‖ = 80 G) that are clearly visible on both signals.

Formula: C12H10N6. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about Towards Langmuir-Blodgett films of magnetically interesting materials: solution equilibria in amphiphilic iron(II) complexes of a triazole-containing ligand. Author is White, Nicholas G.; Feltham, Humphrey L. C.; Gandolfi, Claudio; Albrecht, Martin; Brooker, Sally.

As a first step towards amphiphilic spin crossover (SCO) systems where the hydrophobic part of the system is introduced by a non-coordinating anion (i.e. where no modification of the ligands to introduce hydrophobic substituents is required), [FeII(OH2)2(C16SO3)2] and [CoII(OH2)2(C16SO3)2] have been prepared and reacted with the triazole-containing ligands adpt and pldpt (C16SO3 = hexadecanesulfonate anion, adpt = 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole, pldpt = 4-pyrrolyl-3,5-bis(2-pyridyl)-1,2,4-triazole). In the solid state, two HS complexes of the form [FeII(Rdpt)2(C16SO3)2] and two of the form [CoII(Rdpt)2(CH3OH)2](C16SO3)2 are obtained, even when a six-fold excess of ligand is used (Rdpt = adpt or pldpt). In solution, the cobalt complexes remain in this form as evidenced by color, Visible/NIR and IR spectroscopy. For the iron complexes, there is an equilibrium in solution between the neutral high-spin form of the complex [FeII(Rdpt)2(C16SO3)2] and the dicationic low-spin tris form [FeII(Rdpt)3](C16SO3)2. Polar solvents favor the dicationic form, while less polar solvents favor the neutral form (as evidenced by solution color and solution IR spectroscopy). Visible/NIR spectroscopy and Evans’ method NMR spectroscopy show the equilibrium can be shifted towards the [FeII(Rdpt)3](C16SO3)2 form by adding addnl. ligand to the solution The X-ray crystal structures of [FeII(adpt)2(C16SO3)2] and [CoII(adpt)2(CH3OH)2](C16SO3)2·1.33CH3OH are presented. [FeII(adpt)2(C16SO3)2] has a 2D bilayer structure with alternating layers of polar Fe(adpt)2 centers, and hydrophobic alkyl chains. The complex cations in [CoII(adpt)2(CH3OH)2](C16SO3)2·1.33CH3OH form 1-D columns in the solid state. The capacity of the amphiphilic complexes [FeII(pldpt)2(C16SO3)2] and [FeII(adpt)2(C16SO3)2] to self-assemble has been probed at the air-water interface using Langmuir techniques. The pertinent pressure-area isotherms reveal only a low tendency of the complexes to form films.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine( cas:1671-88-1 ) is researched.Recommanded Product: 1671-88-1.Dupouy, Gaelle; Triki, Smail; Marchivie, Mathieu; Cosquer, Nathalie; Gomez-Garcia, Carlos J.; Pillet, Sebastien; Bendeif, El-Eulmi; Lecomte, Claude; Asthana, Saket; Letard, Jean-Francois published the article 《Cyanocarbanion-Based Spin-Crossover Materials: Photocrystallographic and Photomagnetic Studies of a New Iron(II) Neutral Chain》 about this compound( cas:1671-88-1 ) in Inorganic Chemistry. Keywords: iron cyanocarbanion aminobispyridyltriazole coordination polymer preparation spin crossover; crystal structure iron cyanocarbanion aminobispyridyltriazole coordination polymer; LIESST iron cyanocarbanion aminobispyridyltriazole coordination polymer; photomagnetic study iron cyanocarbanion aminobispyridyltriazole coordination polymer. Let’s learn more about this compound (cas:1671-88-1).

A new Fe(II) chain [Fe(abpt)2(tcpd)] [1; (tcpd)2- = [C10N6]2- = (C[C(CN)2]3)2- = 2-dicyanomethylene-1,1,3,3-tetracyanopropanediide anion, abpt = 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole] was synthesized and characterized by IR spectroscopy, detailed variable-temperature single-crystal x-ray diffraction, and magnetic and photomagnetic measurements. The crystal structure determination of 1 reveals a 1-dimensional structural architecture in which the (tcpd)2- cyanocarbanion acts as a μ2-bridging ligand and the two abpt mols. act as chelating ligands. Detailed x-ray diffraction studies as a function of the temperature (293-10 K) showed a strong modification of the Fe coordination sphere, whose characteristics are in agreement with the presence of a spin-crossover transition from high spin (HS) to low spin (LS) in 1. The average Fe-N distances at room temperature, at 10 K following a flash cooling, and at 10 K after subsequent HS-to-LS relaxation are in the range expected for 100%, 50%, and 25% fractions of HS FeII, resp. These observations are consistent with the presence of ∼25% residual HS species at low temperatures, as derived from the magnetic data. The signature of a photoinduced metastable HS state in 1 was detected by performing coupled photomagnetic and photocrystallog. analyses. The limiting T(LIESST) value associated with the light-induced excited-spin-state trapping effect was derived as 35 K, in good agreement with the thermal dependence of the unit cell volume upon irradiation Kinetic studies governing the photoinduced HS/LS process were recorded at different temperatures; a reverse-LIESST effect was evidenced at 10 K as a reduction of the residual HS fraction by irradiating the sample at 830 nm.
