Synthesis and structural characterization of (pseudo)-halo adducts of (η4-1,5-cyclooctadiene)(1,3-dimethylimidazolin-2-ylidine)rhodium

A series of compounds [(COD)(Me2Im)RhX] (Me2Im=1,3-dimethylimidazolin-2-ylidine, X=Cl, Br, I, N3, NCO, SCN, SeCN) have been prepared and examined using X-ray diffraction and NMR spectroscopy. The synthesis and structure of [(COD)(Me2Bm)RhCl] (Me2Bm=1,3-dimethylbenzimidazolin-2-ylidine) are also reported.
