(2,2′-Bipyridine-κ(2) N,N′)chlorido[4′-(2,5-dimethoxy­phen­yl)-2,2′:6′,2′′-terpyridine-κ(3) N,N′,N′′]ruthenium(II) hexa­fluorido­phosphate acetonitrile monosolvate

In the title compound, [RuCl(C(10)H(8)N(2))(C(23)H(19)N(3)O(2))]PF(6)·CH(3)CN, 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.
