A new organic-inorganic hybrid coordinated polymer [Zn(C8H23N5)]2(Pb3I10) (C8H23N5 = tetraethylene pentamine) was synthesized by hydrothermal reaction. It crystallizes in triclinic, space group P1 with a = 9.781(2), b = 11.442(3), c = 11.565(3) ?, α = 99.075(8), β = 90.540(9), γ = 109.967(5)o, Zn2C16H46N10Pb3I10, Mr = 2399.94, V = 1198.4(5) ?3, Z = 1, Dc = 3.325 g/cm3, F(000) = 1048.0, μ(MoKα) = 17.951 mm-1, the final R = 0.0412 and wR = 0.0993 for 3375 observed reflections with I > 2σ(I). The title compound consists of [Zn(C8H23N5)]2+ cations and anionic chains [Pb3I10]n4n-, which are combined with each other via electrostatic attractive forces and N–H…I hydrogen bonds.

A one dimension solid and a two dimension solid consisting of polyoxoanions bridged by {CoO 3N 2} and {CoO 4} groups respectively have been synthesized by the hydrothermal method and structurally characterized by X Ray crystallography. Each structure has the [(PO 4) 4Mo 6O 15 ] 12- cluster that is commonly observed in many molybdophosphates. In compound 1, [(PO 4) 4Mo 6O 15 ] 12- clusters are linked by {CoO 3N 2} groups to form a chain like structure, and the chains are hydrogen bonded into a network. Compound 2 is a layer structure with channnels constructed from [(PO 4) 4Mo 6O 15 ] 12- clusters and {CoO 4} groups, the organic molecules and the lattice water molecules are distributed disorderly in the interlamellar region and form strong hydrogen bonds with inorganic framework. The IR and the fluorescent spectra were investigated and discussed.

A novel oxalate compound {(H2en)(H3O)[BiPb(C2O4)4(H2O)2]?2(H2O)}n 1 (en = ethylenediamine) containing lead and bismuth has been synthesized by hydrothermal methods, and structurally characterized by X-ray single-crystal diffraction. It crystallizes in monoclinic, space group P21/c with a = 11.6160(1), b = 12.7426(1), c = 15.5683(5) ?, β = 108.442(4)o, BiPbC10N2O21H21, Mr = 921.46, V = 2186.0(4) ?3, Z = 4, Dc = 2.800 g/cm3, F(000) = 1712 and μ(MoKα) = 15.837 mm-1. The final R = 0.0502 and wR = 0.1261 for 3391 observed reflections with I > 2σ(I). The title com- pound consists of 2-D polyanions and protonized organic amine cations, and they are combined to each other by static attractive force and H-bonds to form the so-called organic-inorganic hybrid material.
