A novel three-dimensional supramolecular compound [Ni (DMF) 6] 2 [SiMo12O40] .H2O was synthesized and its structure was characterized by IR, single crystal X-ray diffraction and thermogravimetric analysis. The results show that the title compound belongs to the triclinic system. The space group R3 has the unit cell parameters of a = 1.590 2 (4) nm, b = 1.590 2 (4) nm, c = 3.228 1 ) nm3, Z = 3, Dc = 1.994 g / cm3, μ = 2.032 mm-1, F (000) = 4 146, R1 = 0.051 6 and wR2 = 0.145. Coordination structure of the body surface, crystal packing through a variety of molecular hydrogen bonds formed three-dimensional network structure.
