摘要：

A new organic inorganic hybrid compound based on dawson polyoxotungstate, Na-3(C7NH8O2)(3) [P2W18O62]center dot 16H(2)O have been isolated under autogenous pressure method and characterized by single crystal X-ray diffraction, infrared, ultraviolet spectroscopy, cyclic voltammetry and Thermogravimetric analysis (TGA). This compound crystallized in the triclinic system, space group P-1, with a = 14,063 (1) angstrom; b = 17.009 (1) angstrom; c = 17.868 (1) angstrom; alpha = 79.88 (1)degrees; beta = 77.14 (1)degrees; gamma = 79.25 (1)degrees and Z = 2. The crystal structures of the compounds exhibit three-dimensional supramolecular assembly based on the extensive hydrogen bonding interactions between organic cations, sodium cations, water molecules and Dawson polyoxoanions. The infrared spectrum fully confirms the X-ray crystal structure and the UV spectrum of the title compound exhibits an absorption peak at 295 nm. (C) 2016 Elsevier B.V. All rights reserved.
