Abstract

A mononuclear copper(I) complex, [Cu(ca(2)dapte)]ClO4 (1), and two dinuclear copper(I) complexes, [{Cu(PPh3)(X)}(2)(ca(2)dapte)] (X = 1 (2) and Br (3)), of a new tetradentate N2S2 donor Schiff-base ligand ca2dapte have been prepared (ca(2)dapte = N,N'-bis(trans-cinnamaidehyde)-1,2-di(o-iminophenylthio)ethane). These compounds have been characterized by elemental analyses (CHN), FT-IR, UV-Vis and H-1 NMR spectroscopy. The crystal structures of these copper(l) complexes have been determined by single-crystal X-ray diffraction. The coordination geometry around Cu(I) centers in these complexes is a distorted tetrahedron. The Ca(2)dapte is coordinated to Cu(I) as a tetradentate ligand in 1, while it acts as a bis-bidentate bridging ligand in 2 and 3. (C) 2008 Elsevier Ltd. All rights reserved.
