Abstract

Reaction of [Cp*RhCl2]2 (Cp* = pentamethylcyclopentadienyl) with Ag[closo-CB11H12] affords the dinuclear salt [Cp*RhCl]2[CB11H12]2 (1), which in the solid state reveals a single carborane anion interacting with two {Cp*RhCl} fragments, via two B-H-Rh interactions. With Ag[closo-CB11H6Br6] the trimetallic complex [{Cp*Rh(μ2-Cl)}33-Cl)] [closo-CB11H6Br6]2 (2) results. In the solid state, three metal fragments and four chloride ligands form seven-corners of a cube, and the eighth vertex is completed by a cage C-H unit hydrogen bonded to three bridging chloride ligands.
