trans-Imidazole isomer of the bis(L-histidinato)cobalt(III) complex

L. J. Zompa

Abstract: The title compound, bis(L-histidinato)cobalt(III)-chloride-nitrate-water (1/0.4/0.6/2.5), [Co(C₆H₈N₃O₂)₂]Cl_0.4(NO₃)_0.6·2.5H₂O, crystallizes as a mixed chloride/nitrate hydrate salt. This crystallographic experiment validates earlier research which concluded that the red chromatographic fraction contains the trans-imidazole isomer of the complex. The asymmetric unit contains two complex cations, 0.80-chloride, 1.20-nitrate, and five solvent water molecules.
