Abstract: Tungstogalliumate heteropoly compound containing Cu(Ⅱ)was synthesized and characterized.The results of ESR shows that Cu(Ⅱ)is in the distorted octahedral field. The coordination bond Cu-O is found to be partially covalent.The data of variable temper-ature susceptibility approach Curie-Weiss law,Xm=C/(T-θ).

Key words: tungstogalliumate heteropoly compound, trimetal cluster, ESR, magnetizm
