Abstract

The preparation and characterization of dimeric Cu2(bpy) 2(phga)4 (bpy: 2,2′-bipyridine; phgaH: phenylglyoxylic acid) and Cu2(ba)4(bpy)2 (baH: benzoic acid) complexes are described. Crystallographic characterization of the Cu2(bpy)2(phga)4 complex has shown that the coordination geometry around copper(II) ions is distorted square pyramidal (monoclinic, P21/c, a = 11.7440(4) Å, b = 20.9020(10) Å, c = 9.3980(10) Å, α = 90.00°, β = 93.2240(10)°, γ = 90.00°, V = 2303.3(3) Å3, Z = 4). These complexes were found to exhibit catalase-like activity.
