The redetermined structure of title chalcone derivative, C23H16O2, corrects errors in the title, scheme and synthesis in the previous report of the same structure [Jasinski et al. (2011[Jasinski, J. P., Butcher, R. J., Musthafa Khaleel, V., Sarojini, B. K. & Yathirajan, H. S. (2011). Acta Cryst. E67, o795.]). Acta Cryst. E67, o795]. There are two independent mol­ecules in the asymmetric unit with slight differences in bond lengths and angles. The dihedral angle between the benzene ring and the anthracene ring system is 73.30 (4)° in one mol­ecule and 73.18 (4)° in the other. Both mol­ecules feature an intra­molecular O—H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, mol­ecules are arranged into sheets lying parallel to the ac plane and further stacked along the b axis by ππ inter­actions with centroid–centroid distances in the range 3.6421 (6)–3.7607 (6) Å. The crystal structure is further stabilized by C—H⋯π inter­actions. There are also C⋯O [3.2159 (15) Å] short contacts.

Comment top

From our previous work, which revealed that a chalcone derivative containing the anthracene moiety displayed fluorescence (Joothamongkhon et al., 2010), the title compound (I) was synthesized by changing the substituent group on the phenyl ring for comparison of their properties. It was then discovered that a recent study of the same structure (Jasinski et al., 2011) contained errors in the title, scheme and synthesis. It was found that (I) exhibits fluorescence with the maximum emission at 438 nm when excited at 380 nm in chloroform solution. In addition our experiment shows that (I) also exhibits tyrosinase inhibitory activity with % inhibition of 12.882±8.511 at the concentration 0.125 mg ml-1 when L-tyrosine was used as substrate.

The asymmetric unit of (I) contains two molecules, A and B, with the same configuration but with slight differences in bond lengths and angles. The molecule of (I) (Fig. 1) exists in an E configuration with respect to the C15C16 double bond [1.3392 (15) Å in molecule A and 1.3370 (15) Å in molecule B] and the torsion angle C14–C15–C16–C17 = 177.64 (10)° in molecule A [-179.49 (10)° in molecule B]. The anthracene unit is essentially planar with the r.m.s. 0.0270 (1) Å for molecule A [0.0236 (1) Å for molecule B]. Atom O1 of the prop-2-en-1-one (C15–C17/O1) moiety is deviated from the propene plane with the torsion angle C15–C16–C17–O1 = 18.56 (16)° in molecule A [-17.28 (17)° in molecule B]. The total molecule is twisted as the dihedral angle between phenyl and anthracene rings is 73.70 (4)° and the mean through the pro-2-en-1-one unit makes the dihedral angles of 14.70 (7) and 61.46 (6)° with the phenyl and anthracene rings, respectively [the corresponding values are 73.18 (4), 11.04 (7) and 62.15 (6)° in molecule B]. Intramolecular O2A—H1OA···O1A and O2B—H1OB..O1B hydrogen bonds (Table 1) generate S(6) ring motifs (Bernstein et al., 1995).

The bond distances are comparable with those in the related structure noted above (Joothamongkhon et al., 2010).

In the crystal (Fig. 2), the molecules are arranged into sheets parallel to the ac plane and further stacked along the b axis by ππ interactions with the centroid···centroid distances: Cg1···Cg2ii = 3.6421 (6) Å; Cg1···Cg3ii = 3.6800 (7) Å; Cg2···Cg2ii = 3.7607 (6) Å; Cg4···Cg8iii = 3.6434 (7) Å and Cg5···Cg6ii = 3.7084 (6) Å. The crystal structure is further stabilized by C—H···π interactions (Table 1); Cg1, Cg2, Cg3, Cg4, Cg5, Cg6, Cg7 and Cg8 are the centroids of C1A–C6A, C1A/C6A–C8A/C13A–C14A, C8A–C13A, C18A–C23A, C1B–C6B, C1B/C6B–C8B/C13B–C14B, C8B–C13B and C18B–C23B rings, respectively. C···Oiii[3.2159 (15) Å] short contacts were also observed [symmetry code: (iii) -x, -1/2 + y, 1/2 - z].

Experimental top

The title compound was synthesized by the condensation of anthracene-9-carbaldehyde (2 mmol, 0.41 g) with 2-hydroxyacetophenone (2 mmol, 0.27 g) in ethanol (40 ml) in the presence of NaOH(aq) (10 ml, 40%). After stirring for 4 hr at room temperature, a yellow solid appeared and was then collected by filtration, washed with distilled water and dried in air. Yellow blocks of (I) were recrystalized from acetone by the slow evaporation of the solvent at room temperature after several days, Mp. 431–432 K.

Refinement top

Hydroxy H atoms were located in a difference maps and refined isotropically. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(C—H) = 0.93 Å for aromatic and CH. and the Uiso values were constrained to be 1.2Ueq of the carrier atoms. The highest residual electron density peak is located at 0.71 Å from C1A and the deepest hole is located at 0.43 Å from H1OA.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 120.0 (1) K.

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.
