Abstract top

The crystal structure of a racemic mixture of the title ruthenium(II) complex, [RuCl(C30H30O2P2)2]CF3SO3·2CH2Cl2, reveals that the coordination geometry about the coordinatively unsaturated metal centre is approximately trigonal-pyramidal, with the chlorine atom occupying one of the equatorial positions. The axial Ru-P bonds are longer than the equatorial Ru-P bonds and there is an acute P-Ru-P angle.

Comment top

The development and study of new asymmetric hydrogenation catalysts continues to be a very active area of research (Knowles & Noyori, 2007). Reasons for this interest include the commercial importance of producing enantiomerically pure organic materials (especially for the pharmaceutical industry) and the fact that successful catalysts tend to be substrate-specific rather than being generally useful for a wide range of prochiral substrates (Zhang et al., 2007, Zhang, 2004). Many of the successful catalysts that have been developed contain chiral phosphane or phosphinite ligands (Au-Yeung & Chan, 2004). In our recent studies in this area we have synthesized and studied a range of new chiral ruthenium complexes that are potential asymmetric hydrogenation catalysts (Falshaw et al., 2007, Clark et al., 2009). These complexes all contain chiral diphosphinite ligands that have either chiro-inositol or cyclohexane backbones. During these investigations we prepared a racemic mixture of the cationic, chiral ruthenium complexes [RuCl{(1S,2S)-trans-(OPPh2)2(C6H10)}2]O3SCF3 and [RuCl{(1R,2R) -trans-(OPPh2)2(C6H10)}2]O3SCF3 ((rac)-3) through treatment of a racemic mixture of the corresponding hydride complexes ((rac)-2) with triflic acid (see Figure 1). (rac)-2, in turn, was prepared by heating a solution of [RuCl2(COD)]n with NEt3 and a racemic mixture of the diphosphinite ligands (1R,2R)-1,2-trans-bis-(O-diphenylphosphino)cyclohexane and (1S,2S)-1,2-trans-bis-(O-diphenylphosphino)cyclohexane ((rac)-1). We now report the details of the structure of (rac)-3 which crystallizes with four molecules of each enantiomer in the unit cell. The bond lengths and angles for each enantiomer are crystallographically identical and the structure of [RuCl{(1S,2S)-trans-(OPPh2)2(C6H10)}2]O3SCF3 only is depicted in Figure 2. The geometry about the ruthenium(II) centre in this coordinatively unsaturated complex is approximately trigonal bipyramidal with chloride occupying one of the equatorial positions. It is noteworthy that the isomer of [RuCl{(1S,2S)-trans-(OPPh2)2(C6H10)} 2]O3SCF3 that has the opposite configuration at the metal centre was not present in the crystal. As expected, the two phosphorus atoms in the axial positions (P1 and P4; P1—Ru—P4 = 167.55 (4)°) form slightly longer bonds to ruthenium (Ru—P1 = 2.3935 (13), Ru—P4 = 2.4170 (13) Å) than the two phosphorus atoms (P2 and P3) that are in the equatorial positions (Ru—P2 = 2.2237 (13), Ru—P3 = 2.2430 (13) Å). However, all Ru—P distances fall within the normal range for compounds of this type [Cambridge Structure Database Version 5.30; Allen (2002); average Ru-P(OR)Ph2 distance = 2.288Å (SD = 0.042Å]. Similarly, the Ru—Cl distance (2.3838 (13) Å) is normal. The P2—Ru—P3 angle is small at 87.81 (5)°. The crystals also contain two dichloromethane molecules of crystallization per molecule of complex.

Experimental top

Synthesis of a racemic mixture of chlorobis{(1S,2S)-1,2-trans-bis-(O-diphenylphosphino)cyclohexane}ruthenium(II) trifluoromethanesulfonate and chlorobis{(1R,2R)-1,2-trans-bis-(O-diphenylphosphino)cyclohexane}ruthenium(II) trifluoromethanesulfonate (rac-3). Triflic acid (0.049 ml, 0.56 mmol) was added under nitrogen to a racemic mixture of RuHCl{(1S,2S)-trans-(OPPh2)2(C6H10)}2 and RuHCl{(1R,2R)- trans-(OPPh2)2(C6H10)}2 (0.21 g, 0.19 mmol) in THF (10 ml) and toluene (1 ml). The solution was stirred for 15 minutes at R.T. and the solvents were removed under reduced pressure to give a red product that was recrystallized from dichloromethane/hexane.

Refinement top

Hydrogen atoms were placed in calculated positions and refined using the riding model [C—H 0.93–0.97 Å), with Uiso(H) = 1.2 or 1.5 times Ueq(C). At the completion of refinement, the second parameter of WGHT (55.0) is quite large, possibly as a consequence of the generally weak nature of the X-ray intensity data.

Special details top

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.
