Abstract

{Ru(hfac)(3) (2) was synthesized via peroxide oxidation of the Ru(II) species [Na][Ru(hfac)(3)] (1) (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonate). Treatment of either 1 or 2 with CF3SO3H in MeCN generated cis-Ru(hfac)(2)(MeCN)(2) (3). Ru(acac)(2)(hfac) (4) (acac = acetylacetonate) was generated by addition of hfac to an EtOH solution of cis-[Ru(acac)(2)(MeCN)(2)] [CF3SO3]. Subsequent treatment of 4 with CF3SO3H in MeCN yielded cis-Ru(acac)(hfac)(MeCN)(2) (7). Syntheses of [Na][Ru(hfac)(2)(acac)] (5) and Ru(hfac)(2)(acac) (6) are also reported. The complexes were characterized generally by elemental analysis, cyclic voltammetry, UV-vis, NMR, and IR spectroscopies. The structures of 2,3, and 7 were established by X-ray crystallographic analyses. Crystals of 2 are monoclinic with a = 8.7781(4)
