In the title compound, C17H16BrNO2, the two benzene rings make a dihedral angle of 7.4 (3)°; the hydroxy group links to the carbonyl group via an intramolecular O—H⋯O hydrogen bond. In the crystal, weak C—H⋯O interactions link the molecules into a supramolecular chain running along the c axis.

The title compound (2.0 mmol) was solved in 50 mL methanol. Then the solution was evaporated slowly in the air. Red block crystals suitable for X-ray analysis were obtained after one week.
All H atoms attached to C atoms were fixed geometrically and treated as riding with C—H = 0.95 Å (aromatic) and C—H = 0.98 Å (methyl) with Uiso(H) = 1.2Ueq(C) and Uiso(H) = 1.5Ueq(methyl). H atoms bonded to O atom was located in difference Fourier map and restrained with the H—O = 0.82 (2) Å. In the last stage of
they were treated as riding on the O atom with Uiso(H) = 1.5Ueq(O).Data collection: CrystalClear (Rigaku, 2005); cell

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Organic amine derivatives are becoming increasingly important as new molecule-based crystalline materials with the potential optimal physical properties (Dai & Chen, 2011; Xu et al., 2011). In addition, the amino compounds have found a wide range of applications in coordination chemistry as ligands to construct novel crystal structures (Fu et al., 2011; Zheng, 2011). Herein, we report the crystal structure of the title compound, (E)-1-(5-bromo-2-hydroxyphenyl)-3-(4-(dimethylamino)phenyl)prop-2-en-1-one.
The asymmetric unit is composed of one whole amine molecule. The two benzene rings are nearly coplanar and twisted from each other by a dihedral of 7.4 (3)°. The hydroxy H2 atom was involved in intramolecular O—H···O hydrogen bonds interaction (Table 1 and Fig. 1).
