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.
