p-Cymene Ruthenium Halide Complexes with a Heterocyclic Carbene

The reaction of (p-cymene)Ru(Me2Im)Cl2 with excess Me2ImCO2 in acetonitrile in the presence of NH4PF6 afforded the amino complex [(p-cymene)Ru(Me2Im)(NH3)Cl]PF6. The reaction of (p‑cymene)Ru(Me2Im)Cl2 with excess anhydrous SnCl2 gave the complex (p-cy-mene)-Ru(Me2Im)Cl(SnCl3), whereas treatment of dimeric iodide complex [(p-cymene)RuI2]2 with Me2ImCO2 in acetonitrile gave the ionic compound [Me2ImH][(p-cymene)RuI3].
