Anderson structure derivative (H2en) 3 [(NiO6) Mo6O18 (As3O3) 2] Cl2 · 6H2O (1, en = ethylene-diamine) were prepared and characterized by IR, UV, TG, X-ray powder diffraction and X-ray single crystal structure.The crystal structure of the compound showed that the compound belongs to triclinic system, P-1 space group, : a = 0.94190 (6) nm, b = 1.08612 (8) nm, c = 1.10976 (8) nm, α = 95.6890 (10) °, β = 92.6460 (10) °, = 1.12828 (14) nm3, Z = 1, R1 = 0.0441, wR2 = 0.1189. Compound 1 consists of one [(NiO6) Mo6O18- (As3O3) 2] 4- anion, two Cl- ions, three protonated Ethylenediamine and 6 crystal water, and the heteropolyanion [(NiO6) Mo6O18 (As3O3) 2] 4 is connected to the protonated ethylenediamine and Cl- ions via hydrogen bonds to form a three-dimensional supramolecular structure.
