The preparation and crystal structures of [Ru(bpy) (η2-tpy)(CO)CH2OAc]PF6 and [Ru(η3-tpy)(CO)CH2OAc] PF6 (bpy = 2,2′-bipyridine; tpy = 2,2′:6′,2″ terpyridine)

Abstract:	The first titled compound, 1, was obtained by treating Ru(bpy)(η²-tpy)(CO)CH₂OH]PF₆ with acetic anhydride. Heating 1 in acetonitrile afforded 2, Ru((η³-tpy)(MeCN)(CO) CH₂OAc]PF₆. Allowing 2 to stand in CH₂Cl₂ followed by concentration and precipitation afforded the second titled compound, 3 (Ru((η³-tpy)(CO)–CH₂OAc]PF₆), in which the acetoxymethyl group had become bidentate. Crystal data for 1, monoclinic crystal system, space group C2/c, a=26.001(4) ?, b=13.0395(18) ?, c=20.718(3) ?, β=107.700(2)°, V=6691.7(16) ?³, Z=8; for 3, monoclinic crystal system, space group P2₁/n, a=10.864(2) ?, b=16.922(4) ?, c=11.127(2) ?, β=90.907(3)°, V=2045.4(8) ?³, Z=4.

Keywords:	polypyridyl ruthenium(II) compounds metallacyclization ligand substitution
