Abstract

A dinuclear copper complex containing the ligand 3,6-bis(di-2-pyridylmethyl) pyridazine, bdpdz, [Cu 2(bdpdz) 2](ClO 4) 3, was prepared and its structure determined by X-ray analysis. The compound consists of a dinuclear mixed valence copper(I)-copper(II) entity with localised valences, co-ordinated to two bridging ligand molecules. The geometry around the copper(I) centre is distorted tetrahedral, while that of the copper(II) centre is tetragonally distorted octahedral. Oxidation studies reveal that the compound does not exhibit phenolase activity. © Elsevier Science Ltd.
