Preparation and X-ray crystal structure of bis(pyridinium)-µ-dichloro-µ-oxo-tetrachlorodiantimonate(III); a discrete antimony(III) oxychloro-anion

Abstract

Partial hydrolysis of the polymeric (pyH)₃Sb₂Cl₉(py = pyridine) in ethanol leads to (pyH)₂Sb₂OCl₆ which is shown by X-ray crystallography to contain a discrete oxychloroanion of antimony(III) consisting of two octahedral :SbOCl₄ units sharing a face.
