Abstract: 
Inter­action of the mixed-valent 12-manganese coordination complex [MnIII 8Mn IV 4O 12(CH 3COO) 16(H 2O) 4] with the lacunary 9-tungstoarsenate(V) [A- α-AsW 9O 34] 9− resulted in the 10-­manganese(III/IV)-containing 36-tungsto-4-arsenate(V), [MnIII 6Mn IV 4O 4(OH) 12(H 2O) 12( A- β-AsW 9O 34) 4] 22− (1). Polyanion 1 was isolated as a hydrated mixed potassium–sodium salt, K14Na 8[Mn III 6Mn IV 4O 4(OH) 12(H 2O) 12( A- β-AsW 9O 34) 4]·104H 2O, 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 [MnIII 6Mn IV 4O 4(OH) 12(H 2O) 12] 14+ core stabilized within the 36-tungsto-4-arsenate(V) framework.
