Hydrothermal synthesis and crystal structure of a new layered titanium vanadate decorated with organonitrogen ligand: [Ti(2,2′-bpy)V 2O 7

Abstract

A new organic–inorganic hybrid titanium vanadate [Ti(2,2′-bpy)V 2O 7] 1 (2,2′-bpy2,2′-bipyridine) was synthesized by the hydrothermal reaction of NH 4VO 3, TiCl 4, 2,2′-bpy and water. It was determined by elemental analyses, XPS spectra, TG analysis, IR spectrum and the single-crystal X-ray diffraction. Compound 1 crystallizes in monoclinic system, space group P2/ c, a=9.6083(19) Å, b=9.5196(19) Å, c=14.927(3) Å, β=99.58(3)°, V=1346.3(5) Å 3, Z=4, λ( Mo Kα)=0.71073 Å, ( R( F)=0.0769 for 2632 observed reflections). The title compound contains an unusual two-dimensional titanium vanadate layered network decorated with the 2,2′-bpy ligands.
