Abstract

Reactions between RuCl(Pme3)2(η-C5H5) and unsaturated hydrocarbons in the presence of NH4PF6 have given [Ru(η2-un)(PMe3)2(η-C5H5)] PF6[un = C2H4, (E)-CH(CN)=CH(CN),CH2=CHCH=CH2, CH2=C=CH2, CH2=C=CMe2, C2Ph2, PhC2C2Ph, PhC2CO2Et, C2(CO2Me)2 and C2(CF3)2]. The molecular structures of the buta-1,3-diene (3) and allene (4) complexes have been determined. In both compounds, the unsaturated hydrocarbon is bonded to ruthenium in an asymmetric η2 mode: Ru-C 2.185, 2.242(5) [for (3)], 2.084, 2.172(6) [for (4)l; coordinated C=C 1.386(8), 1.394(8) A, respectively. The allene skeleton is bent by 35� at the central carbon. Crystal data: (3) monoclinic, P21/n, a 17.343(2), b 13.692(4), c 17.997(3) �, β 94.91(1)�, Z 8; (4) orthorhombic, Pca21, a 18.999(3), b 9.253(3), c 23.016(6) �, Z 8. The structures were refined to residuals of R 0.026, R, 0.028 for 4076 data with 1 > 2.5σ(I) [for (3)], and R 0.022, Rw 0.024 for 3054 data [for (4)].
