A novel compound[H-IDP]4[PMo12O40]·8H2O 1 based on Keggin-type phosphormolybdate has been synthesized by hydrothermal method and characterized by IR spectroscopy, elemental analyses and single-crystal X-ray diffraction.The composite crystallizes in the moflo- clinic system,space group C2/m with a=13.937(5),b=27.033(5),C=10.857(5)(A),β= 122.489(5)°.V=3450(2)(A)3,Mr=2611.11,Z=2,Dc=2.498g/cm3,F(000)=2486,μ=2.243 mm-1.the final R=0.0568 and wR=0.1216 for 2707 observed reflections with I>2σ(I).X-ray structural study shows that 1 consists of a[PMo12O40]4- polyanion.four protonated IDP cations and eight H2O molecules.In the structure of 1,a 3D network forms by hydrogen bond of [PMo12O40]4- polyanion,HIDP+cation and H2O molecules.Upon excitation wavelength of 280 nm in hydroxylic solvents at room temperature,1 shows fluorescence property.
