Cyclo(L-histidyl-L-histidyl)copper(II) complexes in aqueous solution

  • 33 Accesses


The structure of the copper(II) complex cation with HISH2 [HISH2 = cyclo(L-histidyl-L-histidyl)] was determined from molecular weight data and n.m.r. and c.d. spectra in aqueous solution. Two HISH2 moieties ligate to coppervia two nitrogen atoms of the imidazole rings giving rise to two 13-membered chelate rings in solution, a situation seen previously in the crystal.

    The apparatus, designed and constructed by Dr. T. Ogura, was modified for the previous report: T. Ogura and R. Casillas,Rev. Soc. Quimi. Mex., 21, 18 (1977). The solution cell was immersed in a thermostat bath and AE caused by the difference of the temperature between solution-solution and solution-solvent was measured. Oguraet al., to be published.
