Abstract: Two Cu(Ⅱ) complexes with title Schiff-base ligand H2L, micro-crystal Cu(HL)ClO4·H2Oand single crystal , have been synthesized and characterized by IRspectra, etc .. By cyclic voltammetry, a quasi-reversible electron-transferring process has been shown in Cu(Ⅱ)/Cu(Ⅰ) couples reaction of [CuL]; the given value E1/20=-0.73 Vhas been estimated. The structure of [CuL] has been determined by X-ray diffraction with R=0.036. The results indicate that the deprotonic ligand, as a practically tetradentate, coordinates only with its two imino and two phenoxo groups to form a D2d symmetric geometry. Two different torsional modes of the homologous ligands, occurring in mono-and di-nuclear Cu(Ⅱ) complexes, respectively, have been contrasted and discussed.
