For the first time, the structure of the half-sandwich complex [(C2B9H11)Mo(CO)3]2- (1) has been determined. The addition of sulfur donor ligands, such as aldrithiol ((C5H4NS)2) and tetraethylthiuram disulfide ((Et2NS)2S2), leads to the partial oxidative decarbonylation of 1 producing mixed half-sandwich complexes, [(C2B9H11)Mo(CO)2(S 2CNEt2)] · (PPN) (2·PPN) (PPN; bis-(triphenylphosphoranylidene)ammonium) and [(C2B9H11)Mo(CO)2(C 5H4NS)] · (NMe4) (3·NMe4). These compounds were characterized both spectroscopically and structurally. Complexes 2 and 3 contain a Mo(II) center in a pseudo pyramidal geometry. Compound 1 · (NMe4)2 is fundamental in affording an entry into the chemistry of new molybdacarboranes with higher formal oxidation states.
