A molybdenum(V) phosphate supported by iron coordination complexes, Fe[Mo6O12(OH)(3)(H2PO4)(HPO4)(2)(PO4)](2)[Fe(2,2'-bipy)(H2O)(2)](2)[Fe(2,2'-bipy)(3)](2)(.)6H(2)O (bipy = 2,2'-bipyridine) 1, has been synthesized by hydrothermal synthesis and characterized. The title complex crystallizes in the monoclinic system, space group P2(1)/c with a = 14.0005(8), b = 25.5229(12), c = 17.9956(9) angstrom, beta = 103.470(2)degrees, V = 6253.5(6) angstrom(3), Z = 2, M-r = 4114.03, D-c = 2.185 g/cm(3), F(000) = 4040, mu = 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.
