Hydrothermal synthesis and structural characterization of organically templated zinc vanadium phosphates: [Zn(2,2'-bipyridine)(VO_2)(PO_4)],[Zn(2,2':6',2'-terpyridine)(VO_2)(PO_4)], and [Zn(1,10-phenanthroline)(ZnVO)(PO_4)_2]

摘要

The hydrothermal reactions of zinc oxide, phosphoric acid, sodium orthovanadate, and the appropriate polyimine ligand at 200 deg C for 95, 68, and 42.5 h, respectively, have yielded three novel compounds, [Zn(bpy)(VO_2)(PO_4)] (1), [Zn(terpy)(VO_2)(PO_4)] (2), and [Zn(o-phen)(ZnVO)(PO_4)_2] (3). Compounds 1 and 2 are both one-dimensional chains with discreet {V_2P_2O_4} rings linked through zinc organoimine components. Compound 3 exhibits unusual {V_2P_4O_(18)} subunits which are bound through fully bridging zinc tetrahedra to form a two-dimensional sheet. The sheet is further surface decorated by {Zn(o-phen)}~(2+) moieties.
