【摘要】 <正> The synthesis of new types of heteropoly compounds is an important aspect in the basic studies on heteropoly acidic catalysts. The ternary heteropoly compounds formed by substituting transition metals for tungsten in 12-heteropoly compounds remain Keggin struc ture with excellent catalystic activity. However, potassium 11-tungstochromate containing transition metals has not been reported. We synthesized Kn[Z （H2O）Cr W11 O39] XH2O (Z=Fe3+, Co2+, Ni2+ and Zn2+) by an improved method. The product was characterized by chemical analysis, ion-exchange, IR, UV and XPS.
