Abstract

Copper(II) complexes with substituted bis(salicylaldehyde) thiocarbohydrazones (3-methoxy = H4LMe, 3-ethoxy = H4LEt), have been synthesized. These ditopic ligands form dinuclear copper(II) complexes containing the ligands in their triplydeprotonated forms. The ligands entail two nonequivalent donor atom sites (ONN and ONS) for copper(II) coordination. Magnetic measurements of the complexes in the temperature range 2–290 K showed significant antiferromagnetic interactions between the two copper(II) ions, with –2J around 180 cm–1. The dinuclear molecules in turn also form face-to-face H-bonded dimers involving four coppers in total.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
