Abstract
Two ligands, N,N′-bis[1-(4-chlorophenyl)ethylidene]ethane-1,2-diamine (L1 ) and N,N′-bis- [1-(4-nitrophenyl)ethylidene]ethane-1,2-diamine (L2 ) and their corresponding copper(I) complexes, [Cu(L 1)2]ClO4 (1) and [Cu(L 2)2]ClO4 (2), have been synthesized and characterized by CHN analyses, 1H-NMR, IR, and UV–Vis spectroscopy. The crystal structures of L1 and [Cu(L 1)2]ClO4 (1) were determined from single crystal X-ray diffraction. L1 lies across a crystallographic inversion center and the C=N is approximately coplanar with the benzene ring and adopts E configuration. The coordination polyhedron about copper(I) in 1 is best described as a distorted tetrahedron. Quasireversible redox behavior is observed for the complexes.
