采用水热合成了一种新型的亚磷酸钒（IV）， （VO）(4)(4,4′-bpy)(2)(HPO(3))(4)，并用单晶x射线衍射对其进行了表征。该化合物结晶为单斜晶系，空间群为C2/c，晶胞参数为a = 35.970(3) a, b = 15.9400(13) a, c = 10.7681(7) a, β = 101.073(4)度，Z = 8， R(1) = 0.0482。该化合物的结构由三角形双锥体[VO(4)N]和伪锥体[HPO(3)]块体组成，它们通过共享角连接，在bc平面上形成亚磷酸钒层。这些层通过4,4英尺宽的柱子进一步连接起来，形成一个3D框架。给出了该化合物的热重分析和磁化率数据。
A novel vanadium(IV) phosphite, (VO)(4)(4,4'-bpy)(2)(HPO(3))(4), was hydrothermally synthesized and characterized by single-crystal X-ray diffraction. This compound crystallizes in the monoclinic system with the space group C2/c and cell parameters a = 35.970(3) A, b = 15.9400(13) A, c = 10.7681(7) A, beta = 101.073(4) degrees, and Z = 8 with R(1) = 0.0482. The structure of the compound consists of trigonal bipyramidal [VO(4)N] and pseudopyramidal [HPO(3)] blocks, which are connected by corner-sharing, to form vanadium phosphite layers in the bc plane. These layers are further linked through 4,4'-bpy pillars, generating a 3D framework. Thermogravimetric analysis and magnetic susceptibility data for this compound are given.
