摘要: 我们测定了四个结构新颖的V-Cu-S簇合物的1H,13C,51V NMR谱.结果表明;在这些异金属簇合物中,存在着Cu+的d电子向V5+的空的d轨道的电子转移,从而加宽了配体R2NCS21H NMR谱线;在溶液中存在着配体交换反应的化学平衡.

关键词: V-Cu-S簇合物, NMR

Abstract: The 1H,13C,51V NMR spectra have been determined for four V-Cu-S cluster compounds at room temperature. The results indicate that he 1H NMR linewidth of ligands R2NCS2 of cluster compounds are broadened, because electron transfarrfrom atom Cu+ to atom V5+ occur;and that several disproportionate reactions by ligand exchange are present in solution.

Key words: V-Cu-S cluster compound, NMR
