摘要

A new one-dimensional Fe(II)molybdophosphate of the formula, [(C_10H_8N_2)N_2]_2[Fe_4~9II)Mo_12~(V)(HPO_4)_6(PO_4)_2(H_2O)_8(OH)_6O_24]·8H_2O, (1), has been synthesized by employing hydrothermal methods and characterized by single crystal X-ray diffraction. The structure consists of a network of MO_6 (M = Fe, Mo) octahedra and (H)PO_4 tetrahedra linked thorugh 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) (A), b = 23.496(5), (A), c = 14.551 (3) (A), #beta# = 114.87(3) deg, V = 3892.5(15)A, and Z = 2.
