[RuCl2(PPh3)3] (20 mg) was dissolved in a mixture of degassed absolute ethanol (2 ml) and freshly distilled CH3CN (3 ml) and stirred for 15 min. During this time, the color of the solution changed from dark brown to yellow. The solvent was removed under vacuum, and the resulting yellow powder was dried for a further 2 h. A 10 mg portion of the solid was dissolved in 0.6 ml of acetonitrile and alllowed to stand for 3 d under nitrogen. Large yellow-orange crystals of the title compound formed over this time. The crystals became opaque due to solvent loss within 20 min of removal from acetonitrile unless placed in a cold stream. The sample used in this study was cut from a larger (>1 mm) block, immersed in Paratone N oil in a 0.5 mm nylon loop, and placed in the nitrogen cold stream of an APEXII diffractometer at 170 (2) K for X-ray diffraction analysis.
Phenyl H atoms were fixed at C—H distances of 0.95 Å and refined as riding, with Uiso(H) = 1.2Ueq(C). Methyl H atoms were placed with idealized threefold symmetry and fixed C—H distances of 0.98 Å, and they were refined in a riding model with Uiso(H) = 1.5Ueq(C). In order to assign the absolute structure, 4387 Friedel pairs (71% of all Friedel pairs) were measured, and Friedel opposites were not merged in the reflection list used for structure solution and refinement. The absolute structure parameter (Flack x) refined to -0.02 (2). For the inverted structure, Flack x refined to 1.02 (2), and increases in R[F2>2σ(F2)] and wR(F2) of 0.33% and 1.29%, respectively, were observed.
[RuCl2(PPh3)3] has been widely used as a convenient synthon for a variety of RuII complexes (Stephenson & Wilkinson, 1966; Hallman et al., 1970). It readily loses one phosphine ligand in solution to give solvent adducts or chlorido-bridged RuII species that are potential catalyst precursors (Caulton, 1974). Gilbert & Wilkinson (1969) previously reported the synthesis of two isomers of [RuCl2(CH3CN)2(PPh3)2] having either cis or trans orientations of the acetonitrile ligands as characterized by infrared spectroscopy. The cis isomer was obtained upon refluxing [RuCl2(PPh3)3] in CH3CN/acetone, whereas the trans isomer was formed upon refluxing in CH3CN/toluene. We found that the cis isomer could also be obtained by stirring [RuCl2(PPh3)3] in CH3CN/ethanol at ambient temperature, confirming the importance of a polar co-solvent in favoring a cis geometry.
The crystal structure of the title compound contains one [RuCl2(CH3CN)2(PPh3)2] complex and two acetonitriles of crystallization in the asymmetric unit. The RuII complex displays a cis orientation of both the chlorido and CH3CN ligands and a trans orientation of the phosphine ligands (Fig. 1). The Ru—Cl [2.4308 (7), 2.4139 (7) Å], Ru—N [2.016 (2), 2.003 (2) Å], and Ru—P [2.3688 (7), 2.3887 (7) Å] distances are in the expected ranges, and the angles between coordinated atoms are in the range 90.02 (6)—93.83 (2)°. In addition to typical C—H···π packing interactions involving phenyl rings, there are several weak hydrogren bonds between C—H bonds of coordinated or solvate acetonitriles and Cl ligands or solvate acetonitrile N atoms (Fig. 2). The H···acceptor distances range from 2.57—2.80 Å, and the C···acceptor distances range from 3.52—3.70 Å (Table 1).
Although it has been little investigated, [RuCl2(CH3CN)2(PPh3)2] is a potentially useful precursor for catalytically active Ru species given the presence of two dissociable ligands in a cis arrangement.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

[RuCl2(PPh3)3] has been widely used as a convenient synthon for a variety of RuII complexes (Stephenson & Wilkinson, 1966; Hallman et al., 1970). It readily loses one phosphine ligand in solution to give solvent adducts or chlorido-bridged RuII species that are potential catalyst precursors (Caulton, 1974). Gilbert & Wilkinson (1969) previously reported the synthesis of two isomers of [RuCl2(CH3CN)2(PPh3)2] having either cis or trans orientations of the acetonitrile ligands as characterized by infrared spectroscopy. The cis isomer was obtained upon refluxing [RuCl2(PPh3)3] in CH3CN/acetone, whereas the trans isomer was formed upon refluxing in CH3CN/toluene. We found that the cis isomer could also be obtained by stirring [RuCl2(PPh3)3] in CH3CN/ethanol at ambient temperature, confirming the importance of a polar co-solvent in favoring a cis geometry.
The crystal structure of the title compound contains one [RuCl2(CH3CN)2(PPh3)2] complex and two acetonitriles of crystallization in the asymmetric unit. The RuII complex displays a cis orientation of both the chlorido and CH3CN ligands and a trans orientation of the phosphine ligands (Fig. 1). The Ru—Cl [2.4308 (7), 2.4139 (7) Å], Ru—N [2.016 (2), 2.003 (2) Å], and Ru—P [2.3688 (7), 2.3887 (7) Å] distances are in the expected ranges, and the angles between coordinated atoms are in the range 90.02 (6)—93.83 (2)°. In addition to typical C—H···π packing interactions involving phenyl rings, there are several weak hydrogren bonds between C—H bonds of coordinated or solvate acetonitriles and Cl ligands or solvate acetonitrile N atoms (Fig. 2). The H···acceptor distances range from 2.57—2.80 Å, and the C···acceptor distances range from 3.52—3.70 Å (Table 1).
Although it has been little investigated, [RuCl2(CH3CN)2(PPh3)2] is a potentially useful precursor for catalytically active Ru species given the presence of two dissociable ligands in a cis arrangement.
