Abstract: Anovel heteropoly tungstomolybdophosphate,[CH3NH3][NH3(CH2)6NH3]H3[P2Mo2W16O62]·H2O has been synthesized and characterized by elemental analysis, IR, TGA-DSC and single-crystal X-ray structure analysis. Crystal data; monoclinic, space group P21/m, a=1.2596(3) nm, b=1.8715(4) nm, c=l. 9816(4) nm, a=γ=90°, β=90. 16(3)° V=4. 671(2) nm3, Z=2, Mr= 4358. 66, Dc= 3. 100 g·cm-3, μ=19. 978 mm-1, F(000)=3792, R=0. 0835, Rw= 0. 2026. The structure analysis shows that a kind of micropore with size of 0. 7364 nm×0. 8354 nm was formed in the crystal structure.
