A Dirhoda-Heterocyclic Carbene.

The linear μ-carbido complex [Rh2 (μ-C)Cl2 (dppm)2 ] (dppm=bis(diphenylphosphino)methane) reacts with dimethylacetylene dicarboxylate (DMAD) to afford [Rh2 (μ-C)(μ-DMAD)Cl2 (dppm)2 ], which features a bent RhCRh linkage (124.7°) that might be described as a dirhoda-heterocyclic carbene, as demonstrated by coordination to further metal centers.
