Research Article: trans-Chloridobis(4-methyl­pyridine-κN)(4,4′,4′′-tri-tert-butyl-2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)ruthenium(II) hexa­fluoridophosphate acetone monosolvate

The title compound, [RuCl(C6H7N)2(C27H35N3)]PF6·C3H6O, was obtained unintentionally as the product of the reaction of 1,1′-methyl­enebis(4-methyl­pyridinium) hexa­fluoriso­phos­phate and RuCl3(tpy*) (tpy* is 4,4′,4′′-tri-tert-butyl-2,2′:6′,2′′-terpyridine) in the presence of triethyl­amine and LiCl. The mol­ecular structure of the complex displays an octa­hedral geometry around the RuII ion and the unit cell contains an acetone solvent mol­ecule and one orientationally disordered PF6− anion (occupancy ratio 0.75:0.25) which is hydrogen bonded to two H atoms of the tpy* ligand of the nearest [RuCl(pic)2(tpy*)]+ cation (pic is 4-methyl­pyridine). One of the tert-butyl groups of the tpy* ligand is also disordered over two sets of sites in a 0.75:0.25 ratio.
