摘要：

The preparation and characterization of dimeric Cu-2(bpy)(2)(phga)(4) (bpy: 2,2'-bipyridine; phgaH: phenylglyoxylic acid) and Cu-2(ba)(4)(bpy)(2) (baH: benzoic acid) complexes are described. Crystallographic characterization of the Cu-2(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)angstrom, b = 20.9020(10) angstrom, c = 9.3980(10) angstrom, alpha=90.00 degrees, beta=93.2240(10)degrees, gamma=90.00 degrees, V=2303.3(3) angstrom(3), Z=4). These complexes were found to exhibit catalase-like activity. (c) 2005 Elsevier B.V. All rights reserved.
