摘　　要：A hybrid organic-inorganic material （H2enMe）[Mo3O10] （C3H12Mo3N2O10, Mr = 523.97） has been synthesized under hydrothermal conditions and its crystal structure was determined by X-ray diffraction. It crystallizes in the orthorhombic system, space group Pnma with a = 12.430（2）, b = 7.6089（12）, c = 11.9553（19）A , V = 1130.7（3）A^3, Dc = 3.078 g/cm^3, Z = 4, μ（MoKa） = 3.328 mm^-1, F（000） = 1000, the final R = 0.0256 and wR = 0.0716 for 1314 observed reflections with I 〉 2σ（I）. A total of 11780 reflections were measured and 1325 were unique （Rint = 0.0244）. It consists of infinite one-dimensional edge-sharing MoO6 octahedral chains with [Mo3O10]^2- moieties. The protonated diaminopropane cations are located between the chains and linked to the oxygen atoms of the inorganic skeletal backbones by hydrogen bonds. It is indicated that the as-synthesized compound displays photochromic property in the solid state.A hybrid organic-inorganic material （H2enMe）[Mo3O10] （C3H12Mo3N2O10, Mr = 523.97） has been synthesized under hydrothermal conditions and its crystal structure was determined by X-ray diffraction.
