(Received 3 March 2011; accepted 15 April 2011; online 18 June 2011)

The molecule of the title complex, [Ni(C₃₀H₂₃O₂P₂)(OH)], adopts a slightly distorted square-planar geometry around Ni^II defined by the coordination of the two mutually trans P atoms, the Csp² atom of the pincer ligand and the O atom of the hydroxide ligand. The largest distortions from ideal geometry are reflected in the smaller than usual P—Ni—P [163.95 (3)°] and P—Ni—C [82.06 (6)°] angles. The OH ligand does not form intra- or intermolecular hydrogen bonds.

Comment top

Pincer-type complexes have attracted much attention recently due to their promise as functional materials and versatile catalysts (Leis et al., 2008; Dijkstra et al., 2001; Naghipour et al., 2007; van der Boom & Milstein, 2003; Nishiyama, 2007). Herein we report the crystal structure and the synthesis of κ^P,κ^C,κ^P-{m-(Ph₂PO)₂C₆H₃}Ni(OH). The formation of the title complex was unexpected in that the original goal of the synthesis was to prepare the corresponding methyl derivative {m-(Ph₂PO)₂C₆H₃}Ni(CH₃). Reaction of the trifluoromethanesulfonate precursor with the Grignard reagent MeMgCl did result in the generation of the target methyl derivative, as ascertained by ³¹P and ¹H NMR spectra of the reaction mixture. It appears, however, that the target methyl complex is not sufficiently stable toward hydrolysis, reacting with residual water during the work-up process to give the observed hydroxo compound. As shown in Fig. 1, the Ni^II ion in the title complex exists in the center of a square plane defined by the donor atoms P1 and P2, the C atom of the aromatic moiety of the pincer ligand, and the O atom of the hydroxyl ligand. A slight tetrahedral distortion is evident in the solid state of this complex despite the rigid meridional coordination of the tridentate pincer-type ligand, but such distortions are commonly found in this family of Ni^II pincer complexes (van der Boom et al., 2003). Perhaps the most surprising aspect of this structure is the absence of inter- or intramolecular hydrogen-bonding type interactions involving the hydroxy group: the closest O—H distance observed in this structure involved a hydrogen of one of the phenyl substituents, but the distance for this interaction is too long to represent a strong interaction (3.080 Å).

Experimental top

Transfer of MeMgCl (0.12 ml of a 1.8 M solution in THF, 0.22 mmol) to a stirred solution of {m-(Ph₂PO)₂C₆H₃}Ni(OSO₂CF₃) (50 mg, 0.073 mmol) Br in dry and degassed toluene (1.5 ml) caused an immediate color change from deep-yellow to red. The resulting mixture was stirred under an inert atmosphere of nitrogen for 5 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. Evaporation of the filtrate gave a red–orange solid, which was crystallized by slow diffusion of hexane into a saturated toluene solution of the crude solid.

Special details top

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 2K charge-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 × 512 pixel mode, utilizing 4 × 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 0.8 Å 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.
