Özet

A novel heterodinuclear Cu(II)-Ni(II) complex of iminooxime ligand has been prepared by employing several steps. The characterization and nature of bonding of the complex have been deduced from elemental analysis, ICP-OES, FT-IR, molar conductivity, magnetic moment measurements and thermal analysis. Elemental analyses, stoichiometric and spectroscopic data of the metal complex indicated that the metal:ligand ratio of the dinuclear Cu(II)-Ni(II) complex have been found to be 2:1. The complex has been tested for enzymatic activity. Kinetic studies have been revealed that the complex exhibited high catecholase-like activity with Michaelis binding constant (K-M=1.9x10(-3)M) and the turnover number (k(cat)=339 h(-1)).
