Hydrothermal Synthesis and Crystal Structure of Iron Molybdophosphate FeMo6O 12(OH)3(H2PO4)(HPO4)2(PO4)2Fe(2,2′-bipy)(H2O)22Fe(2,2′-bipy)32·6H2O

摘要

A molybdenum(V) phosphate supported by iron coordination complexes, Fe[Mo6-dine) 1, has been synthesized by hydrothermal synthesis and characterized. The title complex crystallizes in the monoclinic system, space group P21/c with a = 14.0005(8), b = 25.5229(12), c =17.9956(9) (A), β = 103.470(2)°, V = 6253.5(6) (A)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.
