The supramolecular compounds with molecular composition of [C6H11NH3] 6 [P2 Mo18O62] 4H2O were synthesized by hydrothermal method. The crystal structure analysis shows that the crystal belongs to the monoclinic space group P2 1 with unit cell parameters of a = 1 330 4 (3) nm, b = 2 7910 (6) nm and c = 1 3377 (3) nm, = 118 72 (3) °, Z = 2, V = 4 35 5 9 nm 3, R = 0 0 4 4 3, Rw = 0 0 5 86. Compound molecules by a Wells Dawson structure heteropoly anion P2 Mo18O6-62, six protonated cyclohexylamine and four water molecules. The thermal analysis results show that the heteropolyanion skeleton of the compound decomposes at about 5 6 4 2 ° C
