(Received 23 October 2011; accepted 31 October 2011; online 5 November 2011)

The centroid of the central aromatic ring of the title mol­ecule, C24H22O4, is located on an inversion center. The dihedral angle between the central and terminal benzene rings is 75.00 (7)°. In the crystal, mol­ecules are linked through C—H⋯O hydrogen bonds into chains along [121]. The chains are connected into layers via C—H⋯π inter­actions.

Comment top

We have recently reported the crystal structure of o-acetyl isomer of the title compound (Al-Mohammed et al., 2011). Similar to the previous structure, the title molecule shows a centrosymmetric molecular structure with the centroid of the central benzene ring being located on an inversion center. The central and terminal rings make a dihedral angle of 75.00 (7)°. This value is comparable to those observed in the structures of the previously reported isomer and some other similar compounds (Hu, 2010; Tang et al., 2008). In the crystal, the molecules are linked through C—H···O bonds into chains along [1 2 1] direction. The chains are connected into layers via C—H···π interactions (Table 1, Fig. 2).

Experimental top

To a suspension of α,α'-dibromo-p-xylene (1 g, 3.8 mmol) and potassium carbonate (1.05 g, 7.57 mmol) in dry acetone (25 ml), 4'-hydroxyacetophenone (1.03 g, 7.57 mmole) was added and the mixture was refluxed for 48 hr. The solvent was then evaporated under reduced pressure and the crude material was extracted with dichloromethane (3 x 25 ml). The combined organic layers were washed with water followed by brine and dried over anhydrous sodium sulfate. The solvent was evaporated under vacuum and the formed amorphous solid was re-crystallized from chloroform to obtain colorless crystals of the title compound (m.p. = 435–437 K).

Refinement top

Hydrogen atoms were placed at calculated positions and refined in riding mode with C—H distances of 0.95 (aryl), 0.98 (methyl) and 0.99 (methylene) Å, and Uiso(H) set to 1.2 (1.5 for methyl) Ueq(carrier atoms).

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.
