- 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.
