Crystal structure of cis-[Ru(bpy)₂(PPh₃)Cl⁺][ClO^- ₄]· (toluene)·∼0.5(CH₂Cl₂), a species with two different disordered solvent molecules of crystallization

The complex cis-[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 P1 with a = 10.343(2)Å, b = 11.823(3)Å, c = 18.469(4)Å, a = 98.90(2)°, β = 93.32(2)°, γ = 101.46(2)°, V = 2177.8(8)ų and Z = 2. The structure was refined to R(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)A, 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).
