Description	A room-temperature reaction between the [7-(BuNH)-Bu-t-nido-7,8,9-C3B8H10](-) anion (1a) and [CpRUCl](4) leads to the ruthenatricarbollide [1-Cp-12-(BuNH)-Bu-t-1,2,4,12-RUC3B8H10] (2) (yield 85%). Analogously, the room-temperature photochemical reaction of la with [CpFe(C6H6)]PF6 gives the previously reported iron complex [1-Cp-12-(BuNH)-Bu-t-1,2,4,12-FeC3B8H10] (3) (yield 82%). Both reactions are associated with extensive polyhedral rearrangement, which occurs under very mild conditions and brings the carbon atoms to positions of maximum separation within the framework. Density functional theory calculations at the B3LYP/SDD level were used to estimate relative stabilities of these metallacarborane isomers. The structure of 2 was established by an X-ray diffraction study, and the constitution of all compounds was determined unambiguously by multinuclear NMR spectroscopy, mass spectrometry, and elemental analyses.
