Hydrothermal synthesis and structure of a novel hybrid germanium vanadate: (2,2′-bpy)2(VVO2)2(H2GeO4) · 6H2O

A new hybrid germanium vanadate (2,2′-bpy)2(VVO2)2(H2GeO4) · 6H2O 1 (2,2′-bpy=2,2′-bipyridine) was synthesized by hydrothermal method and structurally characterized by single-crystal X-ray diffraction, thermogravimetric analysis (TGA), IR, XRD and elemental analyses. Crystal data for 1: monoclinic, C2/c, a=16.6937(9) Å, b=11.3501(6) Å, c=17.4774(9) Å, β=118.19(2)°, V=2918.7(3) Å3, Z=4. Compound 1 is composed of the first germanium vanadate skeleton covalently attached to 2,2′-bpy ligands.
