The crystal structure of the title Schiff base compound, C19H20Br2N2O2, contains two crystallographically independent molecules (A and B) in the asymmetric unit, with similar conformations. Intramolecular O—H...N (× 4) and C—H...N (× 5) hydrogen bonds form six- and five-membered rings, producing S(6) and S(5) ring motifs, respectively. One of the N atoms in molecule A acts as a trifurcated acceptor, the rest of the N atoms being bifurcated acceptors. The dihedral angles between the benzene rings in molecules A and B are 47.83 (17) and 61.11 (17)°, respectively. The molecular conformation is stabilized by intramolecular O—H...N and C—H...N hydrogen bonds. The short distances between the centroids of the benzene rings [3.7799 (19)–3.890 (2) Å] indicate the existence of π–π interactions. In addition, the crystal structure is further stabilized by an intermolecular C—H...O hydrogen bond, C—H...π interactions, and short intermolecular Br...Br and Br...O contacts [3.4786 (5) and 3.149 (3) Å, respectively]. |
