- W2048331341 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 CF 3 SO 3 H 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 ][CF 3 SO 3 ]. Subsequent treatment of 4 with CF 3 SO 3 H 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), b = 13.0760(11), c = 19.1857(5) Å, β = 92.2275(5)°, Z = 4, and space group P2 1 /n; those of 3 are monoclinic with a = 25.731(4), b = 8.8332(13), c = 18.1955(4) Å, β = 93.3395(6)°, Z = 8, and space group C2/c; and those of 7 are triclinic with a = 7.6812(9), b = 10.680(2), c = 12.578(2) Å, α = 88.062(6)°, β = 83.874(3)°, γ = 69.5898(15)°, Z = 2, and space group Pbar over 1. The structures were solved by Patterson methods and refined by full-matrix least-squares procedures to R(F) = 0.036, 0.035, and 0.068 (R w (F 2 ) = 0.061,R w (F) = 0.052, and R w (F) = 0.089), respectively.Key words: ruthenium, β-diketonato complexes, acetylacetonate, 1,1,1,5,5,5-hexafluoroacetylacetonate, acetonitrile complexes." @default.
