Abstract

Several alkali metal hydroxoantimonates, K2[Sb(O)(OH) 5], Na[Sb(OH)6], Cs[Sb(OH)6] and Cs 2[Sb2(μ-O)2(OH)8] were isolated from aqueous solutions and characterized by single crystal and powder X-ray diffraction studies and by FTIR and thermal analysis. Crystal structures involving [Sb(O)(OH)5]2- were never anticipated before, and this is also the first disclosure of a dinuclear antimonate [Sb 2(μ-O)2(OH)8]2-. Aqueous antimonate solutions of different pH were studied by high resolution electrospray mass spectrometry showing pH indifferent spectra and predominance of the mono and dinuclear antimonate species at pH 4-10.
