The synthesis products of [CH_3NH_3] [NH_3 (CH_2) _6NH_3] H_3 [P_2Mo_2W_ (16) O_ (62)] · H_2O were synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction. The thermal stability of the compound was investigated. The crystal belongs to the monoclinic space group P2_1 / m with a = 1.259 6 (3) nm and b = 1.871 5 (4) nm, c = 1.981 6 γ = 90 °, β = 90.16 (3) °, V = 4.671 (2) nm ~ 3, Z = 2, M_r = 4 358.66, D_c = 3.100 g · cm -3, μ = 19.978 mm ~ -1), F (000) = 3 792, R = 0.083 5, Rw = 0.202 6. The results show that a micropore of 0.736 4 nm × 0.835 4 nm is formed in the crystal structure.
