Hydrothermal synthesis and structural characterization of organically templated zinc vanadium phosphates:: [Zn(2,2′-bipyridine)(VO2)(PO4)], [Zn(2,2′:6′,2"-terpyridine)(VO2)( PO4)], and [Zn(1,10-phenanthroline)(ZnVO)(PO4)2]

The hydrothermal reactions of zinc oxide, phosphoric acid, sodium orthovanadate, and the appropriate polyimine ligand at 200 degreesC for 95, 68, and 42.5 h, respectively, have yielded three novel compounds, [Zn(bpy)(VO2)(PO4)] (1), [Zn(terpy)(VO2)(PO4)] (2), and [Zn(o-phen)(ZnVO)(PO4)(2)] (3). Compounds 1 and 2 are both one-dimensional chains with discreet {V2P2O4} rings linked through zinc organoimine components. Compound 3 exhibits unusual {V2P4O18} 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.
