    [μ-3,3'-Diisopropyl-1,1'-(propane-1,3-diyl)bis(1,3-diazinan-2-ylidene)]bis[bromido(η4-cycloocta-1,5-diene)rhodium(I)]
    (2014) Pawar, Gajanan Manohar; Wurst, Klaus; Wang, Dongren; Buchmeiser, Michael R.
    The title compound, [Rh2Br2(C8H12)2(C17H32N4)], 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 RhI 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—CNHC distance is 203.8 (7)pm , suggesting that the bond has a major contribution with very little back donation. The distances between the cod ligands and the RhI atoms vary between 210.4 (4) and 221.0 (4) pm.
