✦ Synopsis

The aggregation state of SmI 2 and the reducing power of SmI 2 and its DMPU complex were investigated employing vapor pressure osmometry (VPO) and cyclic voltammetry (CV), respectively. The aggregation number for SmI 2 in acetonitrile was found to be 1.03±0.07 over the entire concentration range studied indicating that SmI 2 is monomeric. The CV study showed that DMPU enhances the reducing power of SmI 2 in acetonitrile but that the resulting complex is not as powerful as the SmI 2 -HMPA complex in THF. The CV study also showed that solvent could alter the reducing power of SmI 2 .
