✦ Synopsis

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) 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.

In this work we have prepared a manganese(II) complex using the tridentate ligand N, N-bis(2-pyridylmethyl)amine (bpma). The manganese complex was characterized by elemental analysis, conductivity measurements and infrared, electronic (UV-vis) and EPR spectroscopic techniques. The analysis of the co
