摘要

A novel organic-inorganic supramolecular compound (C4H6N3)(2)center dot(P2Mo18O62)center dot(C4H7N3)(2)center dot(H2O)(4) was synthesized through hydrothermal methods and characterized by IR spectroscopy, UV-Vis, Fluorescence spectra, TG-DTA, single-crystal X-ray diffraction. The results indicate that the compound exhibit a two-dimensional supramolecular network via hydrogen bond interactions. Crystal data: orthorhombic, Pnma space group, a = 25.4728 (17) , b = 20.3269 (8) , c = 15.6810 (7) , V = 8119.4 (7) (3), Z = 4, R1 = 0.1285, wR2 = 0.2214. There is a pore structure between six [P2Mo18O62](6-) along the b-axis. The accessible volume is 17.9% as estimated using the SOLV function of PLATON. The color of this compound is gradually turned from yellow into green in the ultraviolet irradiation with UV lamp (8W, 253 nm) for 2 h. It is indicated that the compound has photochromic property.
