The hydrothermal synthesis and structure of a one-dimensional Fe(II)molybdophosphate

A new one-dimensional Fe(II)molybdophosphate of the formula, [(C10H8N2)H-2](2)[(Fe4Mo12(V))-Mo-(II)(HPO4)(6)(PO4)(2)(H2O)(8)(OH)(6)O-24]. 8H(2)O, (1), has been synthesized by employing hydrothermal methods and characterized by single crystal X-ray diffraction. The structure consists of a network Of MO6 (M = Fe, Mo) octahedra and (H)PO4 tetrahedra linked through their vertices. The connectivity between the polyhedral units gives rise to one-dimensional chains with eight-membered apertures. The hydrogen bonded interactions between the chains form pseudo two-dimensional layers. Extensive hydrogen bonding also exists between the amine molecule, 4,4'-bipyridine, water molecule and framework oxygen atoms. Crystal data for 1: monoclinic, space group = P2(1) (no. 4), a = 12.549(3) (Angstrom), b = 23.496(5) (Angstrom), c = 14.551(3) (Angstrom), beta = 114.87(3)degrees, V = 3892.5(15) Angstrom (3), and Z = 2.
