The five manganese-containing, Keggin-based tungstosilicates [MnII3(OH)3(H2O)3(A-伪-SiW9O34)]7鈥?/sup> (1), [MnIII3(OH)3(H2O)3(A-伪-SiW9O34)]4鈥?/sup> (2), [MnIII3(OH)3(H2O)3(A-尾-SiW9O34)]4鈥?/sup> (3), [MnIII3MnIVO3(CH3COO)3(A-伪-SiW9O34)]6鈥?/sup> (4), and [MnIII3MnIVO3(CH3COO)3(A-尾-SiW9O34)]6鈥?/sup> (5) were synthesized in aqueous medium by interaction of [A-伪-SiW9O34]10鈥?/sup> or [A-尾-SiW9O34H]9鈥?/sup> with either MnCl2 (1) or [MnIII8MnIV4O12(CH3COO)16(H2O)4] (2鈥?b>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.
