Abstract: In the title compound, [RuCl(C₁₀H₈N₂)(C₂₃H₁₉N₃O₂)]PF₆·CH₃CN, the ligand environment about the Ru^II atom is distorted octahedral, with the substituted terpyridyl ligand coordinated in a meridional fashion, the bipyridyl ligand coordinated in a cis fashion and the Cl atom trans to one of the bipyridyl N atoms. The Ru-N distances are in the range 2.036 (2)-2.084 (2) Å with the exception of the central Ru-N bond from the terpyridyl ligand, which is shorter [1.9503 (19) Å], as expected. The pendant dimethoxyphenyl substituent is not coplanar with the terpyridyl unit; the dihedral angle between the central pyridyl ring and the benzene ring is 46.72 (11)°. The anion is disordered equally over two positions around an F-P-F bond axis.
