Abstract
The title compound, C25H16O, was prepared by the condensation reaction of pyrene-1-carbaldehyde and acetophenone in ethanol solution at room temperature. The phenyl ring forms a dihedral angle of 39.10 (11)° with the pyrene ring system. In the crystal structure, adjacent pyrene ring systems are linked by aromatic π–π stacking interactions, with a perpendicular interplanar distance of 3.267 (6) Å and a centroid–centroid offset of 2.946 (7) Å.

Comment
Chalcone derivatives have always been of interest in the field of inorganic, organic and physical chemists and biology (Strack, 1997) due to their importance in many organic synthetic pathways, biochemical processes and enzymatic mechanisms (Ansari et al., 2005; Pattanaik et al., 2002; Nielsen et al., 2005). In this paper, we report the crystal structure of the title compound, which was obtained by the condensation reaction of pyrene-1-carbaldehyde and acetophenone in ethanol solution at room temperature.
In the title compound, the pyrene ring is substantially planar (maximum displacement 0.011 (4) Å for C12) and forms a dihedral angle of 39.10 (11)° with the phenyl ring. In the crystal packing, adjacent pyrene rings are linked by aromatic π-π stacking interactions, with a centroid-centroid distance of 4.339 (7) Å, a perpendicular interplanar distance of 3.267 (6) Å and a centroid-centroid offset of 2.946 (7) Å.
Experimental
The title compound was prepared by the condensation reaction of pyrene-1-carbaldehyde (0.05 mol) and acetophenone (0.05 mol) in ethanol (20 ml) at room temperature. Single crystals of the title compound suitable for X-ray measurements were obtained by slow evaporation of an ethanol/acetonitrile solution (1:1 v/v) at room temperature.
Refinement
All H atoms were fixed geometrically and were treated as riding on the parent C atoms, with C—H distances of 0.93 Å. Uiso(H) = 1.2 Ueq(C). In the absence of significant anomalous scattering effects, Friedel pairs were merged in the final refinement.

Special details
| 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. |
