Two new compounds, [Ni（en）2]{[Ni（en）2]2[Mo^Ⅵ 6Mo^V2^Ⅳ8O40（SiO4）]}[（NH2）2（C2H4）2NH]·2H2O（1） and [Ni（en）2] { [Ni（en）2]2[Mo^Ⅵ5Mo^V3^Ⅳ8O40（VO4）] } （en）·H2O（2）（en=ethylenediamine）, have been hydrothermally synthesized and characterized by elemental analysis, infrared（IR）, X-ray photoelectron spectroscopy（XPS）, electron spin-resonance（ESR） and thermogravimetric（TG） analysis and single-crystal X-ray diffraction（XRD） analysis, Both the compounds exhibit a 1D chain composed of bi-supporting tetra-capped Keggin clusters and nickle coordination fragments. The ID chains are further assembled into a 3D supramolecular network with different packing modes via hydrogen bonds. The magnetic susceptibiltiy of compound 1 demonstrates the presence of antiferromagnetic interactions.
A novel one-dimensional inorganic-organic hybrid gallophosphate compound, Ga（2,2＇-bipy）（HPO4）. （H2PO4）（denoted JGP-2） was synthesized hydrothermally with 2,2＇-bipyridine as a ligand and characterized by X-ray powder diffraction （XRD）, elemental analysis, inductively coupled plasma（ICP）, TGA analysis, solid-state ^31p NMR, and luminescence spectra and structurally determined by single-crystal X-ray diffraction analysis. JGP-2 crystallized in the triclinic system, space group P^-1（No.2）, with a=0.7818（1） nm, b=0.8611 （2） nm, c=1.0908（2） nm, V=0.6727（2） nm^3 and Z=2 with R1=0.0223. The structure of JGP-2 was built up by alternate arrangement of GaO4N2 octahedra, and HPO4（or H2PO4） tetrahedra to form an infinite one-dimensional corner-sharing-corner（CSC） chain. Through P sites, the CSC chains link with an unusual edge-sharing dimmer, Ga2F4（H2O）2, giving rise to a 4,10-membered ring net layered structure of JGP-7. On excitation at 254 nm, JGP-2 can emit strong blue light at ,λmax=388 rim. JGP-7 presents a strong fluorescence emission band centered at 394 nm（λex=340 nm）, the emission energy of JGP-7 is red-shifted comoared with that of JGP-2.
