Model structures for a copper(I)–copper(II) redox couple in copper proteins: X-ray powder structure of bis(imidazole)copper(I) perchlorate and crystal structure of bis(imidazole)copper(II) diacetate
Abstract
Structural models for the co-ordination geometries of a CuI–CuII redox couple in copper enzymes have been prepared and characterized; they suggest a mechanism for certain copper enzyme reactions where both electrons and protons are involved.
