Abstract: The title compound, bis(L-histidinato)cobalt(III)-chloride-nitrate-water (1/0.4/0.6/2.5), [Co(C6H8N3O2)2]Cl0.4(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.
