| Abstract: | Two organic-inorganic hybrid compounds constructed by 2,2′-biimidazole and Keggin-type polyoxometalate,H3（biim）2]（C4H8O2）2Pw12O40]·11H2O（1）andH3（biim）2]（C4H8O2）3PMo12O40]·3H.O（2）（H2biim=2,2′-biimidazole） have been synthesized under routine synthetic method and characterized by single-crystal X ray diffraction, elemental analysis, IR spectroscopy and electrochemical analysis. The structural analysis shows that compound 1 crystallizes in the monoclin- ic system, C2/c space group, and compound 2 crystallizes in the orthorhombic system, Pbca space group. The 3D frameworks were built by the electrostatic forces and the extensive H-bonding inter- actions among molecules. |
