A new vanadium(Ⅲ) phosphite [V 2(HPO 3) 3(H 2O) 3]·H 2O was synthesized hydrothermally by using V 2O 5, H 3PO 3 and triethylamine as the reactants. 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.
