Abstract The complexcis-[Ru(bpy)2(PPh3)Cl+][ClO 4 − ] (where bpy=2,2′-bipyridyl) crystallizes from a solution in toluene/dichloromethane as the toluene-hemi(dichloromethane) solvate in the centrosymmetric space group $$P\bar 1$$ witha=10.343(2)Å,b=11.823(3)Å,c=18.469(4)Å, α=98.90(2)o, β=93.32(2)o, γ=101.46(2)o,V=2177.8(8)Å3 andZ=2. The structure was refined toR(F)=4.6% for those 4248 reflections above 6σ(F o ). The octahedral Ru(II) cation is associated with the bond lengths Ru−Cl=2.424(2)Å, Ru−PPh3=2.328(1) Å and Ru−N=2.045(5)–2.109(4)Å. Both the cation and the perchlorate anion are ordered. However, the unit cell also contains two disordered toluene molecules (centered about inversion centers at 1, 1/2, 0 and 1/2, 0, 1/2), and a disordered dichloromethane molecule of a partial occupancy (centered about 1/2, 0, 1).
