(Ethane-1,2-di­yl)bis­[bis­(3-methoxy­prop­yl)methyl­phospho­nium] bis­(tetra­phenyl­borate) diethyl ether solvate

Abstract

In the course of substitution studies on the iron dihydrogen complex trans-[Fe(DMeOPrPE)₂(H₂)H](BPh₄) {DMeOPrPE = 1,2-bis­[bis­(methoxy­prop­yl)phosphino]ethane}, we discovered an unexpected transformation of the diphosphine ligand to a diphospho­nium dication without the use of any typical methyl­ating reagent. The P atoms in the dication of the title compound, C₂₀H₄₆O₄P₂ ²⁺·2C₂₄H₂₀B⁻·C₄H₁₀O, have a distorted tetra­hedral coordination with P—C(Me) distances of 1.791 (2) and 1.785 (2) Å. The P—C—C—P torsion angle about the central dimethyl­ene bridge is −168.3 (1)°.

Comment

The bidentate diphosphine ligand 1,2-bis[di(methoxypropyl)phosphino]ethane (DMeOPrPE) has been used in the synthesis of numerous transition metal complexes (Miller et al., 2002; Gilbertson et al., 2005; Crossland et al., 2007). The strong donating ability of this ligand allows these complexes to bind weakly coordinating molecules such as H₂ and N₂ (Gilbertson et al., 2007; Szymczak et al., 2007)). The DMeOPrPE ligand also imparts diverse solubility; often the complexes are soluble in solvents ranging from hexane to water. In the course of substitution studies on iron dihydrogen complexes, specifically trans-[Fe(DMeOPrPE)₂(H₂)H]⁺, we discovered an unexpected transformation of the diphosphine ligand to a phosphonium dication without the use of any typical methylating reagent. At this point the mechanism, by which this diphosphonium is formed, is unclear. We postulate that oxygen atom coordination of a methoxypropyl arm of the DMeOPrPE ligand to the iron center could activate the terminal methyl group for nucleophilic attack by another DMeOPrPE ligand; however, we currently have no evidence for such a mechanism. Alternatively, coordination of acetonitrile to the metal center could activate the methyl group toward nucleophilic attack by the phosphine ligand.

The P atoms in the dication of the title compound [(DMeOPrPE)Me₂]²⁺[BPh₄]₂^-.Et₂O have a distorted tetrahedral coordination with P-C(Me) distances of 1.791 (2) and 1.785 (2) Å. The torsion angle P1-C2-C3-P2 over the central dimethylene bridge is equal to -168.3 (1)°.

Experimental

The dihydrogen complex, trans-[Fe(DMeOPrPE)₂H(H₂)](BPh₄) (DMeOPrPE = 1,2-bis[di(methoxypropyl)phosphino]ethane), was prepared by reported procedures, using NaBPh₄ instead of TlPF₆ (Gilbertson et al., 2007). This complex (0.057 g, 0.053 mmol) was then reacted with the excess of MeCN (0.28 mL, 5.3 mmol) to form trans-[Fe(DMeOPrPE)₂(CH₃CN)H][BPh₄] after 12 hrs (Gilbertson et al.,2007). The acetonitrile complex was not isolated. The resulting solution was layered with Et₂O and allowed to stand at room temperature for 2 months. The title compound formed as pale yellow plates and gave a single ³¹P{¹H} NMR resonance at 38.7 ppm. A ³¹P{¹H} NMR spectrum of the mother liquor revealed two major resonances at 80.9 ppm. and 63.7 ppm., assignable to trans-[Fe(DMeOPrPE)₂(CH₃CN)H]⁺ and trans-[Fe(DMeOPrPE)₂(CH₃CN)₂]²⁺ respectively, as well as a minor amount of the title compound.

Refinement

A highly disordered solvent molecule, most probably Et₂O, was found to be present in crystal; however our attempts to locate the individual atoms were unsuccessful. Therefore, in order to take into account the contribution of the disordered solvent, we applied the SQUEEZE technique (Van der Sluis & Spek 1990). Correction of the X-ray data by SQUEEZE (155 electrons/cell) was close to the expected value for four Et₂O molecules per unit cell (168 electrons/cell). The H atoms were positioned geometrically and refined in the riding model approximation, C—H = 0.95, 0.99 and 0.98 Å; U_iso(H) = 1.2U_eq(C) and 1.5U_eq(C), respectively for –CH, –CH₂ and –CH₃ groups.

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 takeninto account individually in the estimation of e.s.d.'s in distances, anglesand torsion angles; correlations between e.s.d.'s in cell parameters are onlyused 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.
