A novel charge-transfer complex with the composition of (C7H10NO) 3 [PW12O40] .6H2O was synthesized from dodecylphosphonic acid and p-methylaminophenol sulfate by elemental analysis, infrared spectroscopy, solution UV-Vis spectroscopy, It was characterized by X-ray photoelectron spectroscopy, X-ray photoelectron spectroscopy, cyclic voltammetry, thermogravimetric-differential thermal analysis and single crystal X-ray diffraction.The complex crystal belongs to monoclinic system, P2 (1) = 1.504 84 (16) nm, b = 2.966 8 (3) nm, c = 1.504 84 (16) nm, β = 117.82 °, V = 5.941 8 (11) nm3, Dc = 3.753 g / cm3 = 4. The structural analysis shows that the compound molecule consists of one heteropolyanion, three C7H10NO + cations and six crystal water molecules.The electron spectrum shows that in the N, N-dimethylformamide (DMF) solvent or in the solid state Under the organic substrate and heteropolyanions, there exists charge transfer between them, thermal analysis shows that the thermal decomposition of the complex is carried out in three steps, and the decomposition temperature of heteropolyanion is 588.4 ℃.
