The purpose of this study is synthesis, characterization and enzyme activity functions of novel dinuclear metal complexes. Therefore two new dinuclear heterometallic cobat(II)-copper(II) complexes have been synthesized and structurally characterized by using Fourier transform infrared method, elemental analysis, inductively coupled plasma optical emission spectrometry, molar conductivity, magnetic moment measurements and thermal analysis. Spectroscopic and stoichiometric data of the metal complexes indicated that the metal:ligand ratio of the complexes were found to be 2:1. Both of the complexes are 1:2 electrolytes as shown by their molar conductivities and paramagnetism. The subnormal magnetic moment values of the dinuclear complexes were explained by an antiferromagnetic interaction. Additionally complexes were each tested both for their ability to oxidation reaction of 3,5-di-tert-butylcatechol to the 3,5-di-tert-butyl-o-benzoquinone presence of O₂ and catalyse the disproportionation of hydrogen peroxide in the presence of the added base imidazole. It was found that both of the complexes exhibited good catecholase and catalase-like enzyme activity.
