An organic-inorganic hybrid supramolecular complex, (H3O)(4)[(CoC14H12N2O10)(1.5)(SiW12O40)]2H(2)O, is constructed by tungstosilicate anion and 2,3-pyridinedicarboxylic acid cobalt coordination complex via intermolecular forces. Crystal data of the title complex: trigonal system, P-3c1 space group, a=20.363(3)angstrom, b=20.363(3)angstrom, c=27.685(5)angstrom, =90 degrees, =90 degrees, =90 degrees, V=9942(3)angstrom(3), Z=4, R-int=0.0383, R-2=0.1645, GOOF=1.083. The complex has been hydrothermally synthesized and characterized by Infrared spectra, TG-DTA, fluorescence, cyclic voltammetry, and single-crystal X-ray diffraction. The complex exhibits good catalytic activity for elimination of methanol in the gas phase, when the initial concentration of methanol is 2.76gm(-3), and flow rate is 10mLmin(-1) at 140 degrees C, the elimination rate of methanol is 82.6% over 0.2g of complex.
