| 摘 要： | A new dinucleating ligand having two metal-binding sites has been designed and synthesized as model ligand for Cytochrome c Oxidase. The corresponding heterodi-nuclear complex, as an active site model of Cytochrome c Oxidase, consisting of a porphyrinatocobalt compound covalently linked with a copper derivative of tris(2-benzimidazylmethyl) amine bearing three benzimidazole ligands for copper was synthesized and spectroscopically characterized. The spectra data suggest that there are interactions between the cobalt and copper coordination units. The cobalt is coordinated to four central nitrogens of the porphyrin and the copper has pentaco-ordinate geometry with the four tertiary amine nitrogens and a chloride.
