(Received 13 January 2011; accepted 3 March 2011; online 7 April 2011)

The title compound, C13H13O2P, crystallized as enanti­omerically pure crystals; for the crystal measured, the P atom has R stereochemistry. The crystal structure displays O—H⋯O hydrogen bonding, which links individual mol­ecules related by a 21 screw axis parallel to the crystallographic a-axis direction into continuous chains.

Comment top

Phosphinic acids have found use for the construction of coordination polymers [Siqueira et al., 2006; Beckmann et al., 2009] for a wide range of applications [Vioux et al., 2004; Chen & Suslick,1993]. Continuing our research on phosphinic acids [Burrow et al., 2000], we report the synthesis and crystal structure of the title compound, (I).

The crystal structure of (I) is from an enantiomerically pure crystal (Flack parameter = 0.00 (11); 1447 Friedel pairs; Flack & Bernardinelli, 2000] with the P atom possessing R stereochemistry. An analysis of the geometry of (I) by Mogul [Bruno et al., 2004] using the CSD. [Allen, 2002] shows no unusual features for the benzyl and phenyl groups. However, an unusually long PO bond [P1O2 = 1.5104 (13) Å; average in Mogul:1.484 (17) Å for 16 observations, |z score| = 1.568] and a wider C—P—C angle [C11—P1—C21 angle = 109.493 (9)°; average in Mogul: 106.9(2.0) °, |z score| = 1.281] are found.

The individual molecules of (I) related by a 21 screw axis parallel to the crystallographic a direction are joined by hydrogen bonding of the type OH···O=P—OH···O=P to form continuous chains. The short P—O···O=P distance of 2.4838 (18) Å indicates a strong hydrogen bond. This is slightly shorter than the average O···O interaction distance in the CSD. [2.51 (5) Å, 45 observations] for other phosphinic acids.

Experimental top

To a solution of phenylphosphinic acid (2.0 g, 14.1 mmol) in dichloromethane, 30 ml diisopropylethylamine (5.16 ml, 29.6 mmol) and trimethylsilyl chloride (3.74 ml, 29.6 mmol) were separately added at 0 °C under argon. The reaction mixture was stirred at room temperature for 2–3 h, cooled to 0 °C and 1-(bromomethyl)benzene (1.84 ml, 15.5 mmol) was added. After further stirring at room temperature for 48 h, the solvent was removed under vacuum. The residue was suspended in hydrochloric acid (2 M, 20 ml) and filtered on a glass frit. The white solid was washed with acetone and dried giving a yield of 1.70 g (65%) of pure product. IR: 1494 (m), 1439 (s), 1242 (m), 1132 (versus), 1069 (s), 969 (versus), 845 (s), 787 (s), 751 (s), 734 (s), 701 (s), 585 (m), 524 (s), 477 (s), 466 (m) cm-1. TGA: 310–361 °C: 99% loss. DTA: 181–193 °C & 310–361 °C endothermic peaks. Crystals suitable for single-crystal X-ray analysis were grown from an acetone solution in a desiccator with silical gel.

Refinement top

The H atom on O1 was found in the difference Fourier map and its position was allowed to refine freely while its isotropic displacement factor was set to 1.5 times that of O1. The H atoms were positioned geometretically and allowed to ride on their parent atoms, with C—H bond lengths of 0.93 Å (aromatic CH) and 0.97 Å (methylene CH2) and isotropic displacement parameters equal to 1.2 times Ueq of the parent atom.

Special details top

Experimental. SADABS (Bruker, 2009) was used to perform the numeric absorption correction based on the crystal dimensions determined by face indexing.

The number of Friedel pairs measured is 1447. The crystal was not cut to size as it tended to fracture.

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.
