The molecular structure of the title compound, C{sub 21}H{sub 15}Br{sub 1}N{sub 2}O{sub 2}, was characterized by single crystal X-ray diffraction. The compound crystallizes in the triclinic sp. gr. P1̄ with Z = 2. The molecule is not planar: the dihedral angle between the planes of two aromatic rings [C1/C6] and [C16/C21] is 84.9(2)°. The other dihedral angle between two aromatic rings [C9/C14] and [C16/C21] is 88.8(2)°. The title compound exists as a phenol-imine tautomer, in which a strong intramolecular O–H···N hydrogen bond is formed. This study verifies the preference of the phenol-imine tautomeric form in the solid state. A π–π stacking interactions are also observed, which may influence crystal stability: the distance between centroids is 3.702(2) Å.
