Category: isoquinoline. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about New copper(I) complex with triazole derivative ligand containing α-diimine moiety: synthesis, structure, luminescence and electrochemistry. Author is Wang, Wen-Jwu; Lin, Chien-Ho.
One cuprous complex [Cu(L)(PPh3)I] was obtained by reaction of [Cu(PPh3)3I] with a new α-diimine ligand L (N-diphenylmethylene-3,5-di(2′-pyridyl)-4-amino-1,2,4-triazole). The complex was characterized by UV-visible, luminescence, 1H NMR spectroscopy and cyclic voltammetric study. The structure of ligand L and complex are confirmed by single crystal x-ray diffraction study. [Cu(L)(PPh3)I] crystallizes in the monoclinic space group P21/c with a 19.9291(4), b 10.0691(2), c 21.9245(5) Å,β 92.481(10)°, and Z = 4. The complex shows a MLCT band in the 350-545 nm region and exhibits luminescent emission at 600 nm at room temperature in CH2Cl2 solution Cyclic voltammogram of [Cu(L)(PPh3)I] shows a quasi-reversible redox couple of the Cu center at 0.67 V for Cu(I)/Cu(II) and an irreversible reduction potential at -0.98 V accompanied by a stripping peak of Cu at -0.11 V for Cu(I)/Cu(0).
