Abstract

Complexation of copper(II) with penta-coordinated N4S ligands in alcohols proceeded through unusual reaction paths involving C-N bond cleavage process. The products are square planar compound with a modified ligand structure that includes an alkoxy group provided by the solvent. The complexes are characterized by single crystal XRD, elemental analyses, IR, UV-visible and EPR spectroscopic techniques. Cyclic voltammetry shows Cu(II)/Cu(I) reduction becomes more difficult with the increase in donor strength of alkoxy group.
