Abstract
A trinuclear molybdenum cluster having 7 d-electrons, (CpMo)(3)S-4 (1 ), has been synthesized from reduction of CpMo(S(t)Bu)(3) by Na/Hg. E xtended Huckel calculations on (CpMo)(3)S-4 indicate that the unpaired electron resides in the 2e orbital, which is slightly antibonding wit h respect to the cluster atoms. In fact, the Mo3S43+ cluster expands c ompared with a 6 electron Mo3S44+ core. We found evidence for a distor tion of the cluster, albeit very small, due to the Jahn-Teller effect.
