Abstract

A new dinucleating ligand consisting of a tetraphenylporphyrin derivative covalently linked with di(2-benzimidazolylmethyl)imine and its homodinuclear Co-Co and heterodinuclear Co-Cu complexes were synthesized and spectroscopically characterized. The heterobimetallic Co-Cu complex, a cytochrome c oxidase active site model, can be obtained by a simple metathesis reaction of the homodinuclear complex with the metal salt in high yield.
