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 Inhibitor effects of triazole derivatives on corrosion of mild steel in acidic media.COA of Formula: C12H10N6.

The inhibitive action of triazoles on the corrosion of mild steel was studied through weight loss and various electrochem. techniques. Results obtained show that these organic compounds are good inhibitors. Triazoles are able to reduce the corrosion of steel more effectively in 1M HCl than in 0.5 M H2SO4. Potentiodynamic polarization studies clearly reveal the type of inhibitor. Changes in impedance parameters (the charge transfer resistance Rl and the double layer capacitance Cdl) are related to adsorption of triazoles on the metal surface, leading to the formation of a protective film which grows with increasing exposure time. The adsorption of these inhibitors on the mild steel surface in both acids obeys the Langmuir adsorption isotherm. The comparative study of corrosion inhibition of triazole derivatives indicates that the efficiency of the 4-aminotriazole is greater than that of the 4H-triazole.

Eight mononuclear Fe(II) complexes of N4-3,5-di(2-pyridyl)-1,2,4-triazole (Rdpt) ligands were prepared and characterized. In all cases the Fe(II)/ligand ratio used is 1:3, giving red complexes [FeII(Rdpt)3](BF4)2·solvents, in 55-89% yield. The ligands differ only in the nature of the N4-substituent (amino, pyrrolyl, iso-Bu, Me, Ph, para-tolyl, 3,5-dichlorophenyl, and 4-pyridyl; for ligands adpt, pldpt, ibdpt, medpt, phdpt, ptdpt, Cldpt, and pydpt, resp.) allowing substituent effects on the properties of the resulting Fe(II) complexes to be probed. The low temperature crystal structures of seven of the complexes reveal low spin Fe(II) environments. Packing analyses reveal anion-π and MeCN-π interactions involving the tetrafluoroborate counteranions and interstitial MeCN mols., resp. Both π-pockets and π-sandwiches are observed Solid state magnetic susceptibility measurements (4-300 K) indicate the Fe(II) is low spin (LS) in all complexes at all temperatures studied, except for [FeII(pldpt)3](BF4)2·11/2H2O which has the beginnings of spin crossover (SCO) at elevated temperatures Downfield shifts and peak broadening observed in the variable temperature 1H NMR studies indicate that in d3-nitromethane solution the LS [FeII(Rdpt)3]2+ complexes are in equilibrium with a trace of a high spin (HS) species. 15N NMR spectra (measured and calculated) of the ligands reveal that altering the N4-substituent changes the chem. shift of the N1 triazole and pyridine N atoms, allowing probing of the relation between ligand substituent and the nature of the coordinating N atoms.
