In the title complex, [RuCl₂(CH₃CN)₃(C₁₈H₁₅P)]·CH₃CN, the coordination geometry of the Ru^II atom is distorted octahedral, defined by one P atom from a triphenylphosphane ligand, three N atoms from three acetonitrile ligands and two Cl atoms. The three acetronitile ligands linearly bind to the Ru^II atom, with Ru—N—C angles of 172.6 (2), 179.9 (2) and 171.4 (2)°.

Comment top

The structural and reactivity studies of coordinatively unsaturated ruthenium complexes have received much attention due to their versatile and diverse applications in organic transformation (Jansen et al., 2000; Trost et al., 2001). Since Stephenson & Wilkinson (1966) reported [RuCl₂(PPh₃)₃], it has been found that such five-coordinated ruthenium(II) complex readily loses one triphenylphosphane ligand in solution to give a six-coordinated ruthenium(II) complex with a [Ru(PPh₃)₂] moiety (Caulton, 1974). For example, two isomers of [RuCl₂(CH₃CN)₂(PPh₃)₂] were easily obtained upon refluxing [RuCl₂(PPh₃)₃] in a mixed solution with acetonitrile as both co-solvent and ligand (Al-Far & Slaughter, 2008; Gilbert & Wilkinson, 1969), which were firstly characterized by infrared spectroscopy (Hallman et al., 1970) and later confirmed by X-ray crystallography (Al-Far & Slaughter, 2008). We found that a similar reaction of [RuCl₂(PPh₃)₃] in the presence of equal equivalent of hydrogen peroxide resulted in loss of two triphenylphosphane ligands and coordination of three acetonitrile ligands. In this paper, we report the synthesis and crystal structure of a new ruthenium(II) complex [RuCl₂(CH₃CN)₃(PPh₃)].CH₃CN with a [Ru(PPh₃)] species.

In the title complex, the coordination geometry of the Ru^II atom is a distorted octahedral with one triphenylphosphane, three acetonitriles and two chlorides (Fig. 1). The average Ru—N bond distance value, 2.014 (2) Å, is similar to that found in cis-[RuCl₂(CH₃CN)₂(PPh₃)₂] [av. 2.010 (2) Å] (Al-Far & Slaughter, 2008). The Ru—N bond distance of the CH₃CN ligand trans to the chloride ligand is not extended (Jansen et al., 2000; Naskar & Bhattacharjee, 2005). Three CH₃CN ligands are coordinated linearly to the Ru^II atom with average Ru—N—C and N—C—C angles of 174.6 (2)° and 177.3 (2)°, respectively. Average Ru—Cl bond distance [2.4542 (6) Å] is as expected (Al-Far & Slaughter, 2008; Jansen et al., 2000). The Ru—P bond length of 2.2754 (6) Å in the title complex is slightly shorter than those of 2.3688 (7) and 2.3887 (7) Å in the complex cis-[RuCl₂(CH₃CN)₂(PPh₃)₂]. It is interesting to note that the Ru1—Cl2 bond [2.5007 (6) Å] trans to the PPh₃ ligand is ca. 0.1 Å longer than the Ru1—Cl1 bond [2.4080 (6)Å] trans to the CH₃CN ligand. The elongation of the Ru—Cl bond trans to the phosphane ligand is probably due to a relatively strong σ back-bonding from phosphrous to ruthenium.

Experimental top

[RuCl₂(PPh₃)₃] (191 mg, 0.2 mmol) was dissolved in a freshly distilled CH₃CN (10 ml), with stirring at room temperature for 30 min. During this time, the color of the solution was changed from dark brown to orange. Hydrogen peroxide (30%, 6.8 ml, 0.2 mmol) was added to the solution and then the reaction mixture was stirred at reflux for 15 min, developing a yellow. The solvent was evaporated in vacuo and the yellow residue was washed with diethyl ether. Recrystallization from CH₃CN/Et₂O afforded yellow crystals of the title complex within five days. Yield: 127 mg, 69% (based on Ru). Analysis, calculated for C₂₆H₂₇Cl₂N₄PRu: C 52.18, H 4.55, N 9.36%; found C 52.13, H 4.51, N 9.39%.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
