Abstract:The first titled compound, 1, was obtained by treating [Ru(bpy)(2-tpy)(CO)CH2OH]PF6 with acetic anhydride. Heating 1 in acetonitrile afforded 2, [Ru((3-tpy)(MeCN)(CO) CH2OAc]PF6. Allowing 2 to stand in CH2Cl2 followed by concentration and precipitation afforded the second titled compound, 3 ([Ru((3-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) Å, b=13.0395(18) Å, C=20.718(3) Å, =107.700(2)°, V=6691.7(16) Å3, Z=8; for 3, monoclinic crystal system, space group P21/n, a=10.864(2) Å, b=16.922(4) Å, C=11.127(2) Å, =90.907(3)°, V=2045.4(8) Å3, Z=4.
