Abstract The complexcis-[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 $$P\bar 1$$ (No. 2). The structure was refined toR=4.42% for those 6426 reflections with 20=5–50o 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 atx=1,y=1/2,z=0.
