摘要: 报道了十一个含R2NCS2配体的Mo (W)-Cu-S簇合物的,1H NMR研究结果,表明异金属簇合物导致配体中α-H的NMR谱线严重加宽.对谱线的位移,化合物的结构及配位键键长LCu-s之间的关系也作了讨论.

Abstract: The 1H NMR spectra have been determined for eleven Mo(W)-Cu-S metal cluster compounds containing dialkyldithiocarbamate ligands R2NCS2 (R2=Me2,Et2, C4H8, C5H10) at room temperature. The linewidth of α-H (methylene or methyl protons)of the ligands are broadened seriously, because these compounds are heteronuclear. The relation between the shifts of α-H, the structure of the compounds and the average of Cu-S bond lengths is discussed also.
