Synthesis, Structure and Electrochemical Properties of Three-Dimensional Complex [C4H12N2]3[PMo12O40]

The title compound [C4H12N2](3)[PMo12O40] was synthesized from the hydrothermal reaction and characterized by IR, elemental analysis and X-ray signal crystal structural analysis. The crystal of the title complex belongs to trigonal space group R (3) over barc with a=1.788 62 nm, c=2.354 3 nm, and V=6.522 62 nm(3), Z=6, R-1=0.038 4, wR(2)=0.102 0. The compound consisted of piperazine and PMo12O403-, and the structure is extended to three dimensional framework owing to the hydrogen bond between the 0 atoms and N atoms. The bulk-modified carbon paste electrode (APM-CPE) using this compound as modifier shows a good electrocatalytic activity toward the oxidation of ascorbic acid(AA). CCDC: 707968.
