摘　　要：本文测定了一种新型三核钴簇合物(Co_3(bdt)_3(PBu_3)_3]的~1H NMR谱,对谱线作了归属,并和计算机模拟谱进行了比较。本文还讨论了簇合物的分子结构与它的磁性及电子结构之间的关系,并确认它在二氯甲烷溶液中仍保留着固态结构,钴原子之间存在着强烈的反铁磁偶合作用。The 1H NMR of a novel trinuclear cobalt cluster, CCo3(bdt)3(PBu3)3], has been measured at room temperature. The Lines of the spectrum have been assigned, and the simulated spectra were done. Its magnetic and molecular structures were discussed. The results indicate that the cluster is stable in dichloromethane solutilon as the molecular structure remains the same as that in the solid state, and there is strong antiferromagnetic coupling among cobalt atoms in the cluster.
