In the crystal of the title compound, C₁₁H₁₂O₄, inversion dimers arise from pairs of intermolecular O—H⋯O hydrogen bonds and C—H⋯O bonds further consolidate the packing. There is also a C—H⋯π contact between the benzene ring and the methylene group.

Comment top

Benzoyl propionic acids are important intermediates in heterocyclic chemistry and have been used for the synthesis of various biologically active five -membered heterocyles such as butenolides, pyrrolones (Husain et al., 2005), oxadiazoles and triazoles (Hashem et al., 2007). In view of the versatility of these compounds, we synthesized the title compound and reported herein its crystal structure.

In the title compound (Fig. 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. O3, O4, C2, C3 and C4 atoms are 0.067 (3), -0.003 (3), -0.163 (4), -0.013 (3) and 0.016 (3) Å away from the phenyl plane, respectively.

In the crystal structure, intermolecular O-H···O and C-H···O hydrogen bonds (Table 1) link the molecules (Fig. 2), in which they may be effective in the stabilization of the structure. There also exist a C—H···π contact (Table 1) between the phenyl ring and the methylene group.

Experimental top

The title compound was synthesized by the condensation of succinic anhydride (2 g, 20 mmol) with anisol (10 ml) in the presence of alumium chloride (6 g, 42 mmol). The reaction mixture was refluxed for 4 h. After completion of the reaction, excess solvent (anisol) was removed by steam distillation. The resultant solid product was purified by dissolving it in sodium hydroxide solution (5%, w/v), filtering followed by addition of hydrochloric acid. The obtained solid mass was filtered, washed with cold water, dried and crystallized from methanol (yield; 55%, m.p. 419-420 K)

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.
