Abstract top

In the title compound, [Pd(C37H55P2Si)Cl], the Pd atom has a distorted square-planar geometry. The two five-membered rings adopt envelope conformations, while the four cyclohexane rings have chair conformations. The two planar aromatic rings are oriented at a dihedral angle of 28.79 (3)°.

Comment top

Pincer ligands incorporating two phosphine arms and a central donor site have attracted a substantial amount of interest, since the initial investigations of PCP ligands (Moulton & Shaw, 1976). Several variations of the central donor atom have been explored (Boom & Milstein, 2003). However, the "PSiP" pincer-like transition-metal complexes have rarely been reported. The title compound was obtained during our work on the phosphinoalkylsilyl complexes, and we report herein its crystal structure.

In the molecule of the title compound, (Fig. 1), the bond lengths (Allen et al., 1987) and angles are generally within normal ranges. The Pd atom has a distorted square geometry (Table 1). Rings A (C2–C7) and D (C20–C25) are, of course, planar, and they are oriented at a dihedral angle of 28.79 (3)°. The six-membered rings B (C8–C13), C (C14–C19), E (C26–C31) and F (C32–C37) are not planar, having total puckering amplitudes, QT, of 0.570 (3), 0.580 (3), 0.566 (3) and 0.583 (3) and chair conformations [φ = -16.92 (2)°, θ = 2.08 (3)°; φ = -100.91 (3)°, θ = 1.43 (3)°; φ = -40.78 (2)°, θ = 2.27 (3)° and φ = -155.29 (3)°, θ = 176.23 (4)°, respectively] (Cremer & Pople, 1975), while rings G (Pd1/P1/Si1/C2/C7) and H (Pd1/P2/Si1/C20/C25) adopt envelope conformations, with Si1 and Pd1 atoms displaced by -0.422 (3) and 0.694 (2) Å from the planes of the other ring atoms.

Experimental top

Dropwise addition of a solution of MeSiH(Cy2PC6H4)2 (124 mg, 0.21 mmol) in dry THF (5 ml) to a solution of [Pd(COD)Cl2] (43 mg, 0.21 mmol) in a mixture of THF (7 ml) and NEt3 (1 ml) resulted in rapid formation of a colorless precipitate. Removal of the volatiles left solid material, which after through washing left the product (yield; 130 mg, 85%). Crystals suitable for X-ray analysis were obtained by slow evaporation of a benzene (5 ml) solution of the title compound (28 mg) after 1 d.

Refinement top

H atoms were positioned geometrically, with C—H = 0.93, 0.98, 0.97 and 0.96 Å for aromatic, methine, methylene and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

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.
