摘要：

A dinuclear copper(I) complex, [{Cu(PPh3)(I)} 2((mu-L-1)] (1), and a one-dimensional copper(I) coordination polymer, [Cu-2(mu-I)(2)(mu-L-2](n) (2), with two new Schiff base ligands, L-1 = 1,2-bis-[2-(trans-phenylcinnamaldimino)-phenylsulfanyl]-ethane, L-2 = 1,2-bis-[2-(benzaldimino)-phenylsulfanyl]-ethane have been synthesized. The ligands L-1 and L-2 have been prepared by the condensation of 1,2-bis-(2-aminophenylsufanyl)-ethane with beta-phenyl-cinnamaldehyde and benzaldehyde respectively. The ligands and their copper complexes have been characterized by elemental analyses, FT-IR, UV-Vis and H-1 NMR spectroscopy and their structures have been fully confirmed by single-crystal X-ray analysis. The two Schiff bases act as N2S2-bis-bidentate chelating ligands coordinating to Cu(I) centers in an anti-form. The coordination geometry around Cu(I) centers in the two complexes 1 and 2 is a distorted tetrahedron. The electrochemical properties of 1 and 2 have also been investigated by cyclic voltammetry and both copper complexes show irreversible redox behavior. (C) 2013 Elsevier B. V. All rights reserved.
