Novel Carbon Monochalcogenide Coordination Mode: [Rh2{μ-SeCMo(CO)2(Tp*)}24-cod)2] (Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate; cod = cyclo-octa-1,5-diene)

The reaction of [Et4N]­[Mo­(CSe)­(CO)2(Tp*)] (Tp* = hydrotris­(3,5-dimethylpyrazol-1-yl)­borate) with [Rh2(μ-Cl)24-cod)2] (cod = cyclo-octa-1,5-diene) results in the formation of the tetrametallic complex [Rh2{SeCMo­(CO)2(Tp*)}24-cod)2] in which the CSe ligand adopts a crystallographically confirmed and unprecedented μ3:σ,σ′(Se),σ″(C) coordination mode.
