Abstract: | The title complex, [RhBr(C8H12)(C19H22N2O2)], has a distorted square‐planar geometry. There are two molecules, A and B, in the asymmetric unit. The Rh—C bond distance between the N‐heterocyclic ligand and the metal atom is 2.039 (2) Å in molecule A and 2.042 (2) Å in molecule B. The angle between the carbene heterocycle and the coordination plane is 87.56 (12)° in molecule A and 87.03 (11)° in molecule B. It is shown that the average Rh—C(COD) (COD is cyclooctadiene) distance is linearly dependent on the Rh—C(imidazolidine) distance in this type of compound. This can be ascribed to the steric hindrance produced by the packing. The crystal structure contains intramolecular C—H⋯O and intermolecular C—H⋯Br interactions. |
