Preparation and Characterization of K_nGa(H_2O)MW_(11)O_(39)·xH_2O

摘要

In this paper the heteropoly complexes Kn[Ga（H20）MW11O39)]·xH20 [M=Cu（Ⅱ）, Co（Ⅱ）, Cr（Ⅲ）,Fe（Ⅲ）, Mn（Ⅳ）] have been prepared in this laboratory firstly. The products were characterized by chemicalanalysis, ionexchange, IR, UV and X-ray powder diffraction.
