The title compound, [Rh(2)Br(2)(C(8)H(12))(2)(C(17)H(32)N(4))], was obtained by the reaction of 3,3′-(propane-1,3-di­yl)bis­(1-isopropyl-3,4,5,6-tetra­hydro­pyrimidin-1-ium) bromide and [{Rh(cod)Cl}(2)] (cod is cyclo­octa-1,5-diene) in tetra­hydro­furan. The two Rh(I) atoms each have a distorted squ...

Sumario:The title compound, [Rh(2)Br(2)(C(8)H(12))(2)(C(17)H(32)N(4))], was obtained by the reaction of 3,3′-(propane-1,3-di­yl)bis­(1-isopropyl-3,4,5,6-tetra­hydro­pyrimidin-1-ium) bromide and [{Rh(cod)Cl}(2)] (cod is cyclo­octa-1,5-diene) in tetra­hydro­furan. The two Rh(I) atoms each have a distorted square-planar coordination environment, defined by a bidentate cod ligand, a bromide anion and one C atom of the bridging bidentate bis-N-heterocyclcic carbene (NHC) ligand. The average Rh—C(NHC) distance is 2.038 (7) Å, suggesting that the bond has a major σ contribution with very little back donation. The distances between the cod ligands and the Rh(I) atoms vary between 2.104 (4) and 2.210 (4) Å.
