Ruthenium(VI) and osmium(VI) nitrido complexes with halogenated phenoxide and thiophenoxide ligands

Treatment of [Bun4N][Ru(N)Cl4] with Na(OR) afforded [Bun4N][Ru(N)(OR)4] (R = C6F5 (1), C6F4H (2), C6Br5 (3)), whereas that with [Bun4N][Os(N)Cl4] gave [Bun4N][Os(N)(OR)3Cl] (R = C6F5 (4), C6F4H (5), C6Br5 (6)). Treatment of [Bun4N][M(N)Cl4] with Na(SC6F4H) and Na(Sxyl) (xyl = 2,6-dimethylphenyl) afforded [Bun4N][M(N)(SC6F4H)4] (M = Ru (7), Os (8)) and [Bun4N][M(N)(Sxyl)4] (M = Ru (9), Os (10)), respectively. The crystal structures of compounds 1, 6 and 9 have been determined.
