Abstract: A summary of the latest results in the authors' laboratories covering three areas is presented. The results of the controlled syntheses of oxide ion encapsulating lanthanacarboranes, by the introduction of stoichiometric amounts of H₂O in the synthesis reactions, and the strictures of the resulting compounds were discussed. The scope and limitations of a general method for the synthesis of the open pentadienyl complexes were presented. In addition, the results of a systematic study of the reactions of the [2,n-(SiMe₃)₂-nido-2,n-C₂B₄H₄]^2- (n = 3, 4) with the late transition-metal salts MCl₂ (M = Fe, Co, Ni) were discussed.
