{2,6-Bis[(diphenyl­phosphan­yl)­oxy]phen­yl-κ³ P,C ¹,P′}iodidonickel(II)

Abstract

In the title complex, [Ni(C₃₀H₂₃O₂P₂)I], the divalent Ni atom is coordinated by two P atoms and one C atom from the 1,3-bis­[(diphenyl­phosphan­yl)­oxy]benzene ligand; the distorted square-planar geometry is completed by an iodide ligand. The largest distortions from ideal square-planar geometry are reflected in the P—Ni—P angle of 164.20 (2)° and the P—Ni—C angles of 82.09 (6) and 82.11 (6)°. The rather short Ni—C bond length [1.890 (2) Å] is anti­cipated in light of the much stronger trans influence of the aryl moiety compared to the iodide ligand. The P-bound phenyl rings adopt different orientations to minimize steric repulsion among themselves.

Comment

Recently, much attention has been paid to the chemistry of pincer complexes (Leis et al. 2008; Dijkstra et al. 2001; Naghipour et al. 2007; van der Boom et al. 2003; Nishiyama 2007). These compounds have found applications as promising materials and highly versatile catalysts. Here we report the crystal structure and the synthesis of{m-(Ph₂PO)₂ C₆H₃}NiI. The formation of the title complex was serendipitous in that the original goal of the synthesis was to prepare the corresponding methyl derivative {m-(Ph₂PO)₂C₆H₃}Ni(CH₃). To our surprise, reaction of the bromo precursor with the Grignard reagent MeMgI gave instead the iodo derivative. It appears that the target methyl complex is not sufficiently stable, undergoing a salt metathesis with MgX₂ (X= Br or I) to furnish the iodo derivative. As shown in Fig. 1, the Ni(II) center in the title complex exists in the center of a square plane defined by the donor atoms P1 and P2, the iodide ligand, and the carbon atom of the aromatic moiety of the pincer ligand. Despite the rigid meridional coordination of the tridentate pincer-type ligand, a slight distortion is evident in the solid state of this complex from the P—Ni—P angles of 82.09 (6) and 82.11 (6)°; such distortions are commonly found in this family of Ni(II) pincer complexes (van der Boom et al. 2003).

Experimental

Transfer of MeMgI (0.12 ml of a 3.0 M solution in THF, 0.24 mmol) to a stirred solution of {m-(Ph2PO)2 C6H3}NiBr(50 mg, 0.08 mmol) in dry and degassed toluene (1.5 ml) caused an immediate color change from deep yellow to a red orange. The resulting mixture was stirred under an inert atmosphere of nitrogen for 15 min and was then filtered through cellulose. Evaporation of the solvent gave an orange solid. Single crystals suitable for X-ray diffraction studies were grown by slowly diffusing hexane into a saturated toluene solution.

Refinement

All hydrogen atoms were positioned geometrically and refined as riding, with C—H = 0.93 Å, and U_iso(H) = 1.2 U_eq(C).

Special details

Experimental. X-ray crystallographic data for I were collected from a single-crystal sample, which was mounted on a loop fiber. Data were collected using a Bruker Platform diffractometer, equipped with a Bruker SMART 2 K Charged-Coupled Device (CCD) Area Detector using the program SMART and normal focus sealed tube source graphite monochromated Cu—Kα radiation. The crystal-to-detector distance was 4.908 cm, and the data collection was carried out in 512 x 512 pixel mode, utilizing 4 x 4 pixel binning. The initial unit-cell parameters were determined by a least-squares fit of the angular setting of strong reflections, collected by a 9.0 degree scan in 30 frames over four different parts of the reciprocal space (120 frames total). One complete sphere of data was collected, to better than 0.8Å resolution. Upon completion of the data collection, the first 101 frames were recollected in order to improve the decay correction analysis.

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.
