摘要
A new compound has been synthesized under hydrothermal conditions and characterized by IR, elemental analysis, XPS and single-crystal X-ray diffraction analysis. The title compound [Mn（en）3]2en0.5[HV8VV8IVO38（CI）]·4.5H2O crystallizes in monoclinic, space group C2/c, with a = 17.016（4）, b = 18.858（4）, c = 18.872（4） A, β = 93.667（4）°, V = 6043（2）A3, Z = 4, Dc = 2.242 g/cm3, Mr = 2040.12, F（000） = 4020,μ = 2.895 mm-1, Rint = 0.0921, R = 0.0649 and wR = 0.1325. Single-crystal X-ray structure analysis indicates that the title compound consists of a polyanion [HV8VV8IVO38（CI）]4- cage, two [Mn（en）3]2^2＋ cations, four and a half lattice waters and a half ethylenediamine. In addition, intermolecular O-H...N, O-H...O, N-H...O and C-H...O hydrogen bonds link the molecules together to form a three-dimensional structure.
