✦ Synopsis

PMR and absorption spectra have been used to estabiish the structure of N~(r~)-~ut~~bione complexes in aqueous solutions -at various pH values. Equilibria exist between a few octabedra1 and square phnar complexes in soiution. At pH above I I the most stable complex is formed by the coordination of the Ni(iI) ion to the cyateine residue. Ni(II) is bound to the sulphur atom and deprotonated nitrogens of the peptide A linkage form the square planar complex.
