Abstract

The complex cis-[Ru{4,4′-(t-Bu)₂bpy}₂(PPh₃)Cl ⁺][ClO^-₄] · 0.5(toluene) · 0.5(MeCN), where 4,4′-(t-Bu)₂bpy = 4,4′-di(t-butyl)-2,2′-bipyridyl, crystallizes with an ordered racemic mixture of the chiral cations in the centrosymmetric triclinic space group P1 (No. 2). The structure was refined to R = 4.42% for those 6426 reflections with 2θ = 5-50° and |F_o| > 6σ(F). Ruthenium ligand distances are Ru-Cl = 2.423(2)Å, Ru-PPh₃ = 2.346(2)Å and Ru-N = 2.056(4)-2.098(4)Å. Both the Ru(II)-containing cation and the perchlorate anion are ordered, but the toluene and acetonitrile exhibit an interesting type of scrambled disorder about the inversion center at x = 1, y = 1/2, z = 0.
