摘要: 合成并表征了铜的钨镓杂多化合物α-Na7H4[GaW9O37Cu3(H2O)3]·18H2O.ESR 结果表明,Cu2+处于变形的八面体配位场中,Cu—O键有一定程度的共价性.变温磁化率分析结果表明,Cu3O13中铜离子间存在铁磁相互作用,J=—4.8×10-22J.

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
