Chlorido(chloro­diphenyl­phosphine-κP)(diphenyl­piperidinophosphine-κP)(η⁵-penta­methyl­cyclo­penta­dien­yl)ruthenium(II)

Abstract

The title compound, [Ru(C₁₀H₁₅)Cl(C₁₂H₁₀ClP)(C₁₇H₂₀NP)], is a half-sandwich complex of Ru^II with the chloro­diphenyl­phosphine ligand formed from the diphenyl­piperidinophosphine and chlorine of the precursor complex [Ru(η⁵-C₅Me₅)(κ¹P—Ph₂PNC₅H₁₀)Cl₂] by an unexpected reaction with NaBH₄. The complex has a three-legged piano-stool geometry, with Ru—P bond lengths of 2.2598 (5) Å for the chloro­phosphine and 2.3303 (5) Å for the amino­phosphine.

Comment

We found that halfsandwich ruthenium aminophosphine complexes [Ru(Cp')(κ¹P—Ph₂PNRR')₂(CH₃CN)₂]⁺ (Cp' is either Cp = cyclopentadienyl or Cp* = pentamethylcyclopentadienyl; Ph = phenyl; NRR' = NHⁿPr, NEt₂, or NC₅H₁₀ = piperidin-1-yl) react with diynes to afford novel η³-phosphaallyl-η²-vinylamine complexes and may transform under certain conditions to aminocarbenes (Pavlik et al., 2006). In continuation of this work we were interested to react [Ru(Cp*)(κ¹P—Ph₂PNC₅H₁₀)Cl₂], a Ru(III) complex, with NaBH₄ in order to obtain a hydrido or borohydride complex. After workup of the reaction, NMR spectra indicated that another unknown Ru complex must have formed which was studied subsequently with X-ray diffraction and is reported here. The title compound, (I), turned out to contain, in addition to an intact piperidinodiphenylphosphine (Ph₂PNC₅H₁₀), a chlorodiphenylphosphine as the second phosphine ligand of a half-sandwich complex with a three-legged piano-stool structure (Fig. 1). It is a Ru^II complex with the chemical formula [Ru(Cp*)(κ¹P—Ph₂PCl)(κ¹P—Ph₂PNC₅H₁₀)Cl] that bears similarities to [Ru(Cp*)(κ¹P—Ph₂PCl)₂Cl] (Torres-Lubia et al., 1999) with respect to stereochemistry of the complex, but also with respect to its formation. In case of [Ru(Cp*)(κ¹P—Ph₂PCl)₂Cl] the chlorophosphine was not directly introduced but formed from [Ru(Cp*)(κ¹P—Ph₂PH)₂Cl] (Ph₂PH = hydridodiphenylphosphine) in CDCl₃ as the solvent in the presence of the strong base DBN (1,5-diazabicyclo[4.3.0]non-5-ene) by a stepwise chlorine/hydride exchange between the solvent and the two hydridophosphines. In a related way the title compound must have formed from [Ru(Cp*)(κ¹P—Ph₂PNC₅H₁₀)Cl₂] and NaBH₄. However, there were no chlorinated solvents present in our reaction and the chlorine of the generated chlorophosphine must originate from the starting complex. It can be speculated that the formation of the title compound involves the intermediary formation of a hydridodiphenylphosphine, which by a hydride/chloride substitution leads to the chlorodiphenylphosphine of the title compound obtained in a poor yield of only 9%. A related and also unexpected transformation of a thiol-substituted hydridodiphenylphosphine into a thiol-substituted chlorodiphenylphosphine was observed in the reaction with Mn(CO)₅Br in chloroform (Liu et al., 1995). Bond lengths and angles in the title compound (see Table 1 and supplementary materials) are similar to those of [Ru(Cp*)(κ¹P—Ph₂PCl)₂Cl] (Torres-Lubia et al., 1999), which has <Ru—C> = 2.246 (20) Å (2.245 (21) Å for (I)), Ru—P = 2.242 (2) and 2.257 (2) Å, Ru—Cl = 2.438 (2) Å, and P—Cl = 2.085 (3) Å. Both Ru complexes adopt related conformations and have in common that the Ru-bonded and the P-bonded Cl lie on opposite sides. In both complexes the phosphine ligands adopt orientations that lead to a stabilization by intramolecular π-π-stacking between the two adjacent phenyl rings (Fig. 1) with a shortest contact distance of C(12)···C(28) = 3.183 (3) Å in the title compound (ring-ring centroid distance 3.717 (2) Å, ring-ring inclination angle 12.96°). Moreover, it is remarkable that the title compound shows eight intramolecular C—H···Cl/N interactions (seven to Cl, one to N), but only one intermolecular C—H···Cl interaction (see supplementary materials).

Experimental

The synthesis of [Ru(Cp*)(κ¹P-PPh₂NC₅H₁₀)(κ¹P-PPh₂Cl)Cl], (I), was carried out as follows: A solution of [Ru(Cp*)Cl₂]₂ (322 mg, 0.52 mmol) (Oshima et al., 1984) in THF (10 ml) in THF (10 ml) was treated with Ph₂PNC₅H₁₀ (300 mg, 1.2 mmol) and the solution was stirred for 1 h at room temperature. After that NaBH₄ (150 mg, 4.0 mmol) was added and the mixture was stirred for 12 h. After evaporation of the solvent an oily residue was obtained from which the product was extracted with pentane (2 x 10 ml). The volume of the solution was then reduced to about 0.5 ml whereupon red crystals of the title compound were obtained. Yield: 42 mg (9%). ¹H NMR (C₆D₆, 293 K, δ, p.p.m.): 7.50 - 6.51 [m, 20H, Ph], 3.03 – 2.72 [m, 4H, CH₂], 1.40 [s, 15H, Cp*], 1.33 – 1.26 [m, 4H, CH₂], 1.00 – 0.89 [m, 2H, CH₂]. ¹³C{¹H} NMR (C₆D₆, 293 K, δ, p.p.m.): 137.1 – 125.7 [Ph], 93.2 [Cp*], 45.86 [CH₂], 26.2 [CH₂], 24.6 [CH₂], 8.9 [Cp*]. ³¹P{¹H} NMR (acetone-d₆, 293 K, δ, p.p.m.): 93.1 [d, J_HP = 37.2 Hz, PPh₂Cl], 36.0 [d, J_HP = 38.5 Hz, PPh₂N]. Crystals for X-ray diffraction were obtained by cooling a pentane solution to -20°C.

Refinement

All H atoms were placed in calculated positions, with C—H = 0.93–0.98 Å, and were thereafter treated as riding, with U_iso(H) values of 1.5U_eq(C) for methyl groups and 1.2U_eq(C) for others.

Special details

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.
