A new vanadium(Ⅲ) phosphite,V2(HPO3)3(1),was synthesized hydrothermally with V2O5,H3PO3 as reactants,1,6-diaminopropane(1,6-HAD) as the structure-directing agent and characterized by single crystal X-ray diffraction,powder X-ray diffraction,IR spectroscopy,TGA,ICP-AES and elemental analyses.Single-crystal X-ray diffraction analysis reveals that compound 1 crystallized in the P6(3)/m hexagonal space group with the unit-cell parameters:a=0.80436(10) nm,c=0.73972(2) nm,V=0.41447(13) nm3,Z=4.The construction of 3D framework structure of compound 1 may be viewed as the assembly of V2O9 dimers and HPO3 pseudo-pyramids which lead to form the one-dimensional 4,12-member ring channels along the [001] direction.
