硫化钼簇单元[Mo 6S 8（PEt 3）6]（1）与CH 3 OTf的甲基化导致形成单甲基和二甲基化簇单元[Mo 6S 8-x（SCH 3）x（PEt 3）6]OTf·yCH 2Cl 2 {[2]OTf·0.5CH2Cl2（x= 1，y= 0.5）和[3]OTf·CH 2Cl 2（x= 2，y= 1）}。结构和电化学研究表明，µ3-S配体的甲基化诱导了[Mo 6S 8]簇核心的特征结构畸变，并增强了其接受多个电子的能力。
Methylation of the molybdenum sulfide cluster unit [Mo6S8(PEt3)6] (1) with CH3OTf resulted in the formation of mono‐ and dimethylated cluster units, [Mo6S8–x(SCH3)x(PEt3)6]OTf·yCH2Cl2{[2]OTf·0.5CH2Cl2(x= 1,y= 0.5) and [3]OTf·CH2Cl2(x= 2,y= 1)}. Structural and electrochemical investigations revealed that the methylation of the µ3‐S ligand(s) induced a characteristic structural distortion of the [Mo6S8] cluster core and enhanced its ability to accept multiple electrons.
