Structure and optical activity in metal complexes, vi. Interaction of histidine with copper(ii) in solution.
The species existing in aqueous solution at pH 8.3 when copper(II) interacts with two equivalents of L-histidine has been studied by a variety of techniques. The evidence is consistent with a fluctuating type of coordination for the histidinato-copper(II) complex, which varies according to conditions and other coordinating ligands involved.
