The Cu and O(1) are in special positions. The anions are the unusual hydrogensulfate (HSO4-) which have remarkably short acceptor H bonds to the same coordinating H2O mol. (O(1)-O(13) (1-x, y, 0.50-z) = 2.701(4), H(1)-O(13) (1-x, y, 0.50-z) = 1.74(4) Å, O(1)-H(1)···O(13) (1-x, y, 0.50-z) = 167(4)°).

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about In Situ Solvothermal Generation of 1,2,4-Triazolates and Related Compounds from Organonitrile and Hydrazine Hydrate: A Mechanism Study.Related Products of 1671-88-1.

The facile and effective one-pot solvothermal syntheses of 3,5-disubstituted 1,2,4-triazole and its derivatives (substituted group = alkyl, aryl, and pyridyl) through cyclocondensations of organonitriles and hydrazine hydrate in the absence/presence of metal salts have been established. By control of the solvothermal conditions and/or the addition of counter anions, different intermediates and final products were derived from various organonitriles, in which an intermediate N,N’-bis(picolinamide)azine (H4bpa) has been successfully trapped in its neutral manganese(II) complexes. A systematical study shows that, after the initial formation of 2-pyridylamidrazone from 2-cyanopyridine and hydrazine, two reaction paths are involved in the formation of 1,2,4-triazoles: via the formation of 3,6-bis(2-pyridyl)-1,2-dihydro-1,2,4,5-tetrazine and H4bpa as intermediates. The tetrazine and H4bpa paths are preferred in the absence and presence of metal ions, resp. In the presence of metal ions, metal ion binding can stabilize the tautomers, enhance the nucleophilic reactivity of the imino C atom, and inhibit the tautomerization of H4bpa, hence leading to the formation of 1,2,4-triazolates or H4bpa in complexed forms. The in situ cyclocondensation reactions of 2-pyridylamidrazone and carboxylate into asym. 3,5-disubstituted 1,2,4-triazolates under solvothermal conditions have also been observed for the first time. Crystal structures of the crystalline metal complexes have been obtained, including dinuclear [Mn2(bpt)2Cl2(H2O)2] (1) and [Mn2(bpt)2(SCN)2(H2O)2] (3; Hbpt = 3,5-bis(2-pyridyl)-4H-1,2,4-triazole), tetranuclear [Mn4(H3bpa)2(mpt)4(N3)2]·2H2O (5; Hmpt = 3-methyl-5-(2-pyridyl)-1H-1,2,4-triazole), [Mn4(H3bpa)2(pt)4(N3)2]·2C2H5OH (6; Hpt = 5-(2-pyridyl)-1H-1,2,4-triazole), and [Mn4(H3bpa)4(SCN)4]·2C2H5OH (7), as well as helical [Cu(bpt)] (2).

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine(SMILESS: NN1C(C2=NC=CC=C2)=NN=C1C3=NC=CC=C3,cas:1671-88-1) is researched.Related Products of 58081-05-3. The article 《Cooperative Spin Crossover and Order-Disorder Phenomena in a Mononuclear Compound [Fe(DAPP)(abpt)](ClO4)2 [DAPP = [Bis(3-aminopropyl)(2-pyridylmethyl)amine], abpt = 4-Amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole]》 in relation to this compound, is published in Inorganic Chemistry. Let’s take a look at the latest research on this compound (cas:1671-88-1).

The synthesis and detailed characterization of the new spin crossover mononuclear complex [FeII(DAPP)(abpt)](ClO4)2, where DAPP = [bis(3-aminopropyl)(2-pyridylmethyl)amine] and abpt = 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole, are reported. Variable-temperature magnetic susceptibility measurements and Mossbauer spectroscopy revealed the occurrence of an abrupt spin transition with a hysteresis loop. The hysteresis width derived from magnetic susceptibility measurements is 10 K, the transition being centered at Tc↓ = 171 K for decreasing and Tc↑ = 181 K for increasing temperatures The crystal structure was resolved in the high-spin (293 and 183 K) and low-spin (123 K) states. Both spin-state structures belong to the monoclinic space group P21/n (Z = 4). The thermal spin transition is accompanied by the shortening of the mean Fe-N distances by 0.177 Å. The two main structural characteristics of [Fe(DAPP)(abpt)](ClO4)2 are a branched network of intermol. links in the crystal lattice and the occurrence of two types of order-disorder transitions (in the DAPP ligand and in the perchlorate anions) accompanying the thermal spin change. These features are discussed relative to the magnetic properties of the complex. The electronic structure calculations show that the structural disorder in the DAPP ligand modulates the energy gap between the HS and LS states. In line with previous studies, the order-disorder phenomena and the spin transition in [Fe(DAPP)(abpt)](ClO4)2 are interrelated.

Although many compounds look similar to this compound(1671-88-1)Formula: C12H10N6, numerous studies have shown that this compound(SMILES:NN1C(C2=NC=CC=C2)=NN=C1C3=NC=CC=C3), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
