Abstract

Imidazolate-bridged Cu(II)–Zn(II) heterodinuclear and Cu(II)–Cu(II) homodinuclear hydroperoxo complexes are generated in the reactions between imidazolate-bridged heterodinuclear and homodinuclear complexes and H₂O₂ in the presence of triethylamine base and characterized spectroscopically as reaction intermediate models of Cu,Zn–SOD.
