    Abstract: One cuprous complex [Cu(L)(PPh3)I] was obtained by reaction of [Cu(PPh3)3I] (PPh3 = triphenylphosphine) with a new a-diimine ligand L (N-diphenylmethylene-3,5-di(2'-pyridyl)-4-amino-1,2,4-triazole). The complex has been characterized by UV-Vis, luminescence, 1H NMR spectroscopy and cyclic voltammetric study. The structure of ligand L and complex are confirmed by single crystal X-ray diffraction study. The compound [Cu(L)(PPh3)I] crystallizes in the monoclinic P21/c space group with a = 19.9291(4), b = 10.0691(2), c = 21.9245(5), α = γ = 90, 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 dichloromethane solution. Cyclic voltammogram of [Cu(L)(PPh3)I] shows a quasi-reversible redox couple of the copper 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 copper at -0.11 V for Cu(I)/Cu(0).
