Abstract
The reaction of CuCl2 · 2H2O and CdCl2 with di-(2-picolyl)sulfide (dps) leads to the formation of mononuclear copper(II) and binuclear cadmium(II) complexes, [Cu(dps)Cl2] · H2O (1) and [(dps)(Cl)CdII(μ-Cl)2CdII(Cl)(dps)] (2). The copper atom in (1) is coordinated to one sulfur and two nitrogen atoms from the dps ligand and two chlorides in a distorted square-pyramidal environment. Complex (2) has two distorted octahedra sharing the basal edge that contain the bridging chloro ligands, each of which resides at a center of inversion. Cyclic voltammetric data show that (1) undergoes two reversible one-electron waves corresponding to CuII/CuIII and CuII/CuI processes. However, cyclic voltammetry of (2) gives two irreversible reduced waves.
