| Abstract: A new metalorganic-inorganic hybrid compound [Cu4(phen)4(HPO4)2(H2O)2(OH)2][HPMo12O40]·H2O (1)(phen=1,10-phenanthroline), has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, thermal analysis and single-crystal X-ray structural analysis. Compound 1 is consisted of a tetranuclear copper phosphate [Cu4(phen)4(HPO4)2(H2O)4(OH)4]2+, Keggin polyoxoanion [HPMo12O40]2- and the lattice water molecule. Compound 1 generates an interesting 2D network between the tetranuclear copper phosphates and polyoxoanions by weak M…O interactions (M=Cu, Mo), which is further connected into a 3D supramolecular architecture through hydrogen bonds and π-π interactions. Compound 1 was used as a solid bulk modifier to fabricate a carbon paste electrode (1-CPE) by direct mixing. The electrochemical and electrocatalytic behaviors of the 1-CPE have been studied in detail. CCDC: 666620. |
