| Abstract: | A 1D chain-like organic/inorganic composite material with polyoxovanadates serving as building blocks has been synthesized by the reaction of cyclohexylamine with vanadium pentoxide, and characterized by IR, UV spectra and TG-DTA technique. The title compound (C3oH7oN5O15V5, Mr = 995.61) crystallizes in orthorhombic, space group P2 12 1 21 witha = 6.0093(12), b = 26.780(5), c = 27.979(6) A, V = 4502.6(16) A3, Z = 4, Dc = 1.461 g/cm3,F(000) = 2060, μ = 1.063 mm-1, R= 0.0651 and wR= 0.1084 for 3426 observed reflections (I ＞2σ(I)). Single-crystal X-ray structural analysis indicates that the title compound consists of five proto- nated cyclohexylamine molecules and a polyoxovanadate anion of VsO155-. In addition,the results of IR spectra and single-crystal X-ray diffraction exhibit that there exists comparatively stronger interaction between the organic groups and polyoxovanadate anion in solid state. Adjacent structure units are bridged through comer-sharing oxygen atoms of VO4tetrahedra to construct a novel one-dimensional zigzag infinite linear chain arrangement. The curves of TG- DTA elucidate that the process of weight loss of the title compound is divided into two stages, and also reveal that the framework of polyoxovanadate anion decomposes at 473.0 ℃. |
