Five New Chlorochromates of Organic Bases

We have synthesized and characterized live new chlorochromate(VI) complexes of organic bases: 4,4'-bipyridinediium bis [chlorochromate(VI)], (C10H10N2)[CrO3Cl](2), 4-methylquinolinium chlorochromate(VI), (C10H10N)[CrO3Cl], 6-methylquinolinium chlorochromate(VI), (C10H10N)[CrO3Cl], N,N'-ethylenediaminium chloride chlorochromate(VI), (C2H10N2)(C1) [CrO3Cl] and (5-chloro-2-pyridyl)(2-pyridyl)ammonium chlorochromate(VI), (C10H9CIN3)[CrO3Cl]. The crystal and molecular structures of these compounds have been determined by X-ray crystallography and show that organic cations are bound to [CrO3Cl](-) anions by significant N ... O and C ... O hydrogen-bonding interactions.
