Abstract:

Interaction of the mixed-valent 12-manganese coordination complex [MnIII8MnIV4O12(CH3COO)16(H2O)4] with the lacunary 9-tungstoarsenate(V) [A-α-AsW9O34]9- resulted in the 10-manganese(III/IV)-containing 36-tungsto-4-arsenate(V), [MnIII6MnIV4O4(OH)12(H2O)12(A-β-AsW9O34)4]22- (1). Polyanion 1 was isolated as a hydrated mixed potassium-sodium salt, K14Na8[MnIII6MnIV4O4(OH)12(H2O)12(A-β-AsW9O34)4]·104H2O, which crystallizes in the orthorhombic space group Pbcn and was characterized by FT-IR spectroscopy and single-crystal X-ray diffraction, as well as elemental and thermogravimetric analyses. The title polyanion contains a unique [MnIII6MnIV4O4(OH)12(H2O)12]14+ core stabilized within the 36-tungsto-4-arsenate(V) framework.
