| Abstract: | A novel inorganic-organic compound (C4N2H12)(C2N2H10)2Mo5P2O23] (1) has been synthesized by the reaction of (NH4)2MoO4, H3PO4, C2N2H8 (ethylenediaminium), C4N2H10·6H2O (piperazine hexahydrate) and water in aqueous solution under mild hydrothermal conditions. Single-crystal X-ray analysis reveals that the title compound is crystallized in the triclinic system, space group P1 with a = 9.258(19), b = 9.382(19), c = 17.681(4), α = 76.28(3), β = 84.48(3), γ = 70.82(3)o, V = 1408.9(6)3, Mr = 1122.04, Z = 2, Dc = 2.645 g/cm3, μ = 2.384 mm-1, F(000) = 1092.0, the final R = 0.0391, wR = 0.1185 and S = 1.006 for 6169 observed reflections with I > 2σ(I). The crystal packing is stabilized by intra- and intermolecular N–H···O hydrogen bonds to form an infinite 3D network. |
