Synthesis and characterization 9-tungstosilicate complexes with transition metal

  • Published:
Wuhan University Journal of Natural Sciences

Abstract

The title complexes KaHb[M(SiW9O34)2mH2O(M=Ni,Cu,Zn,Fe or Mn) were synthesized by SiW9O34 10− with transition metal respectively and their structure were characterized by mean of elemental analysis, TG-DTA, IR spectra and, UV spectra. In addition, their redox properties in solution were investigated using polarographic and cyclic voltammographic methods. Experimental results indicated that the complexes have Keggin structure and that the heteropolyanions underwent two-step, two-electron tungsten reduction processes.
