Abstract

A mononuclear copper(I) complex, [Cu(ca2dapte)]ClO4 (1), and two dinuclear copper(I) complexes, [{Cu(PPh3)(X)}2(ca2dapte)] (X = I (2) and Br (3)), of a new tetradentate N2S2 donor Schiff-base ligand ca2dapte have been prepared (ca2dapte = N,N′-bis(trans-cinnamaldehyde)-1,2-di(o-iminophenylthio)ethane). These compounds have been characterized by elemental analyses (CHN), FT-IR, UV-Vis and 1H NMR spectroscopy. The crystal structures of these copper(I) 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 ca2dapte is coordinated to Cu(I) as a tetradentate ligand in 1, while it acts as a bis-bidentate bridging ligand in 2 and 3.
