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

Abstract

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.
