The as-synthesized product was characterized by powder X-ray diffraction, IR spectroscopy and ICP analysis. The result of single-crystal X-ray diffraction analysis shows that the title compound crystallized in the monoclinic space group P2 1(No.4) with the parameters a=0.783 9(2) nm, b=1.020 6(3) nm, c=0.824 7(2) nm, β= 112.510(4)°, V= 0.609 6(3) nm 3, Z=2. Its structure is built up by alternation of octahedral VO 5(H 2O), VO 4(H 2O) 2 and pseudo-pyramidal HPO 3 units to generate a three-dimensional framework structure where there exist water molecules.展开更多
An organically templated vanadium phosphate phosphite, [V2O2（OH）（HPO3）（HPO3）0.75（PO3OH）0.3]（C6N2H16）0.5 （1）, was hydrothermally synthesized and characterized by single crystal X-ray diffraction.

Compound 1 crystallizes in monoclinic system, space group C2/c with cell parameters a=1.305 58（18） nm, b=1.020 69（10） nm, c=1.909 8（2） nm, V=2544.9（5） nm3 and Z=8. It possesses a layered architecture and organic template molecules located between the inorganic layers forming hydrogen bonds. The inorganic layers are constructed of V（Ⅳ）O5 square pyramid, [PO3OH2-] pyramid and [HPO2-3] pseudo pyramid by sharing vertices.展开更多
