Abstract

The five manganese-containing, Keggin-based tungstosilicates [Mn ^II₃(OH)₃(H₂O)₃(A-α- SiW₉O₃₄)]^7- (1), [Mn^III ₃(OH)₃(H₂O)₃(A-α-SiW ₉O₃₄)]^4- (2), [Mn^III ₃(OH)₃(H₂O)₃(A-β-SiW ₉O₃₄)]^4- (3), [Mn^III ₃Mn^IVO₃(CH₃COO)₃(A- α-SiW₉O₃₄)]^6- (4), and [Mn ^III₃Mn^IVO₃(CH₃COO) ₃(A-β-SiW₉O₃₄)]^6- (5) were synthesized in aqueous medium by interaction of [A-α-SiW₉O ₃₄]^10- or [A-β-SiW₉O₃₄H] ^9- with either MnCl₂ (1) or [Mn^III ₈Mn^IV₄O₁₂(CH₃COO) ₁₆(H₂O)₄] (2-5) under carefully adjusted reaction conditions. The obtained salts of these polyanions were analyzed in the solid state by single-crystal X-ray diffraction, IR spectroscopy, and thermogravimetric analysis. The salts of polyanions 1, 2, and 4 were further characterized in the solid state by magnetic studies, as well as in solution by electrochemistry.
