C17H24Cl2N2Ru, monoclinic, P121/c 1( no. 14), a =1 5.010(5) A, b =7 .825(3) A, c =2 0.903(5) A, * =1 33.20(1)°, V =1 789.8 A 3 , Z =4 , Rgt(F) =0 .059, wRref(F 2 ) =0 .113, T =2 98 K. Source of material [RuCl2($ 6 -p-cymene)]2 (0.245 mg ,0 .4 mmol) dissolved in dichloromethane (20 mL )w as treated with N,N-dimethylpyridin-4amine (DMAP, 0.098 mg, 0.8 mmol). The orange-red solution was heated under reflux for 1h ,c ooled to room temperature, filtered and evaporated to 2m Lu nder reduced pressure. Then it was layered with petroleum ether and filtered to give orange-red residue. The solid residue was washe ds everal time sw ith petroleum ether. It is soluble in dichloromethane, acetone, and methanol. Orange-red crystals were obtained by crystallization from dichloromethane/petroleum ether (yield 0.21 mg ;6 1.2 %). Experimental details All Ha tom sw ere positioned geometrically and allowed to ride on thei rp aren ta toms at distances of d(Csp 2 —Hpyridyl )=0 .93 Aa nd d(Csp 2 —Hp-cymene )=0 .98 Aw ith Uiso =1 .2 Ueq(parent atom) and d(Csp 3 —H) =0 .96 Aw ith Uiso =1 .5 Ueq(parent atom).
