Hexaaquagallium Hexahydrogenhexamolybdocobaltate(III) Decahydrate

The structure of hexaaquagallium(III) hexahydrogentetracosaoxocobalt(III)hexamolybdate decahydrate, [Ga(H₂O)₆][Co(OH)₆Mo₆O₁₈].10H₂O, includes a polyanion with the so-called Anderson structure, of general formula H₆[Xⁿ⁺Mo₆O₂₄]^(6-n)- (X is a heteroatom), where all the O atoms in the central XO₆ octahedron are protonated. The Ga³⁺ ion is coordinated by six water molecules and the Co³⁺ ion by six O atoms. Both ions are located at inversion centers.
