B. J. Boro, D. A. Dickie, K. I. Goldberg and R. A. Kemp

In the title compound, [Ni(C₂₄H₄₃P₂)Cl], the Ni atom adopts a distorted square-planar geometry, with the P atoms of the 2,6-bis[(di-tert-butylphosphino)methyl]phenyl ligand trans to one another. The P-Ni-P plane is twisted out of the plane of the aromatic ring by 21.97 (6)°.

Comment top

The title compound, (I), was originally prepared by Moulton & Shaw (1976) but its crystal structure was not determined at that time. We have prepared (I) as part of our studies of PCP 'pincer' complexes of divalent late transition metals, which show promise as catalysts for the epoxidation of olefins (Denney et al., 2006; Keith et al., 2006).

In the molecular stucture of (I) (Fig. 1), the nickel adopts a square planar geometry, with the phosphorus atoms trans to one another. The Ni—P bond lengths 2.1921 (4) and 2.1978 (4) Å, are significantly shorter than the corresponding Pd—P bonds [2.3039 (6) and 2.3969 (6) Å] in the analogous palladium complex (Kimmich et al., 2002). Steric hindrance distorts the P—Ni—P bond angle to 169.651 (18)°, while the less constrained C—Ni—Cl angle is much closer to linearity at 176.13 (5)°.

Significant geometrical changes are observed in the 2,6-bis[(di-tert-butylphosphino)methyl]benzene ligand upon binding to nickel. In the free ligand (Hollink et al., 2003), the average P—C_methylene bond length is 1.870 Å, while in (I), it has decreased to 1.8308 (19) Å (P1—C8) and 1.8341 (18) Å (P2—C7). This bond shortening is accompanied by change in the P—C_methylene—C_phenyl angle, from 114.5° in the free ligand to 106.23 (12)° (P1—C8—C2) and 106.84 (12)° (P2—C7—C6) in (I).

Experimental top

A solution of nickel chloride hexahydrate (0.6 g, 2.5 mmol) dissolved in 2 ml of degassed water was added to a solution of 2,6-bis-[(di-tert-butylphosphino)methyl]benzene (1.02 g, 2.6 mmol) in 10 ml ethanol. The solution was heated to reflux. A golden-yellow precipitate began to form only after 0.5 h. The solution was stirred under gentle reflux overnight. After cooling, the product was collected by filtration and washed with cold ethanol. It was recrystallized from a concentrated solution of pentane at 238 K.

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.
