A molybdenum(V) phosphate supported by iron coordination complexes, Fe[Mo6- O12(OH)3(H2PO4)(HPO4)2(PO4)]2[Fe(2,2?-bipy)(H2O)2]2[Fe(2,2?-bipy)3]2?6H2O (bipy = 2,2?-bipyri- dine) 1, has been synthesized by hydrothermal synthesis and characterized. The title complex crys- tallizes in the monoclinic system, space group P21/c with a = 14.0005(8), b = 25.5229(12), c = 17.9956(9) ?, β = 103.470(2)°, V = 6253.5(6) ?3, Z = 2, Mr = 4114.03, Dc = 2.185 g/cm3, F(000) = 4040, μ = 1.931 mm-1, R = 0.0438 and wR = 0.1168. The structure of the title polyoxometalate anion is based on a centrosymmetrical cluster Fe[Mo6O12(OH)3(H2PO4)(HPO4)2(PO4)]2 supported by two [Fe(2,2?-bipy)(H2O)2] subunits. The 2D network is formed through intermolecular hydrogen bonds.
