Halogeno-oxydiantimon(III)ates

Abstract

Compounds in the halogeno-oxydiantimonate series, [Hpy]₂[Sb₂OBr_nCl_6–n][n= 0–6, Hpy = pyridinium(1+)], have been synthesised by partial hydrolysis from related [Hpy]₃[Sb₂Br_nCl_{9 –n}] species and characterised by vibrational spectroscopy and mass spectrometry. The hexachloride [Hpy]₂[Sb₂OCl₆] also results from the action of adventitious water on solutions of antimony(III) chloride and pyridine.
