A novel compound [H-IDP]4[PMo12O40]·8H2O 1 based on Keggin-type phosphor- molybdate has been synthesized by hydrothermal method and characterized by IR spectroscopy, elemental analyses and single-crystal X-ray diffraction. The composite crystallizes in the mono- clinic system, space group C2/m with a = 13.937(5), b = 27.033(5), c = 10.857(5), β = 122.489(5)°, V = 3450(2) 3, Mr = 2611.11, Z = 2, Dc = 2.498 g/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.
