Cg1 is the centroid of atoms C1–C6, Cg2 is the centroid of atoms C10–C15 and Cg3 is the centroid of atoms C17–C22.
A solution of 10% aqueous NaOH (10 ml) and 30 ml me thanol was taken in a conical flask. Benzaldehyde (0.02 mol) and p-amino acetophenone (0.01 mol) were dissolved in 30 ml me thanol and the mixture was added to the conical flask with vigorous stirring. After stirring the solution for 90 minutes, the content were poured into a beaker containing ice cold water and allowed stand for overnight. The resulting precipitate was washed with excess of water, filtered and dried. The compound was purified by successive recrystallization from acetone. Yellow chunks of (I) were obtained by slow evaporation of an acetone solution.
The hydrogen atoms were placed in calculated positions (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).

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. |

As part of our ongoing studies of organic nonlinear optical materials derived from substituted chalcones (Harrison et al., 2007), we now report the synthesis and structure of the title compound, (I), (Fig. 1). It is centrosymmetric, therefore it does not display any second harmonic generation response.
The dihedral angle between the central (C10—C15) and terminal (C1—C6 and C17—C22) aromatic rings are 49.62 (4)° and 48.20 (4)°, respectively. The dihedral angles for the enone (C7/C8/C9/O1) fragment with respect to C1—C6 and C10—C15 are 25.47 (9)° and 24.37 (8)°, respectively. Overall, the molecule of (I) is substantially twisted.
The only possible directional interactions in (I) are weak C—H···π links (Table 1), with each of the three benzene rings accepting one such bond (Fig. 2).
