The reaction of phosphomolybdodecanoic acid, ammonium metavanadate, CuCl 2 · 2H 2 O and 3,3 ’, 5,5’-tetramethyl-4,4’-o-diazepine (H 2 X) , A new polyoxometalate Cu_4 (H_2X) _4 [(PMo_ (12) O_ (40) (VO) _ (0.5))] was synthesized and characterized by X-ray single crystal diffraction, The structure of the compound was characterized by X-ray diffraction, reanalysis and other means. The crystal structure analysis of the compound shows that the compound is a 2D layered compound belonging to the monoclinic space group C2 / c with a = 2.637 6 (5) nm, b = 1.542 2 (5) nm, c = 2.057 0 (5) nm, α = 90.000 (5) °, β = 112.677 (5) ° and γ = 90.000 (5) °, 3, Z = 4, R_1 = 0.061 5, wR_2 = 0.164 6.
