| 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[HV16O38(Cl)]·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) (A)3, 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(Cl)]4( cage, two [Mn(en)3]22 cations, four and a half lattice waters and a half ethylenediamine. In addition, intermolecular O-H…N，O-H…O and C-H…O and C-H…O hydrogen bonds link the molecules together to form a three-dimensional structure.
