Syntheses of three stable complexes of Cr(V) have been described which were characterised by elemental analysis,ir, electronic spectral,esr and magnetic studies. The size and charge of the counter ion determines the overall composition of the Wienland salts. Apparently the isolation of oxotetra-, penta- and hexachlorochromates(V) of benzimidazolium, biquinolinium and terpyridinium cations respectively were achieved. These oxochlorochromates possibly contained the same oxotetrachlorochromate(V) species.
