formula [RuCl2(arene)(κ1-dpim)] (dpim = 2-(diphenylphosphino)-1-methylimidazole) (arene = p-cymene, 1a; C6H6, 1b) were prepared by the reaction of [RuCl2(p-cymene)]2 or [RuCl2(C6H6)(CH3CN)] with dpim. Complexes 1a and 1b were structurally characterized by NMR spectroscopy and X-ray diffraction. The reaction of these precursors with BF4- salts led, in dichloromethane, to cationic complexes of formula [Ru
