(E)-3-{[(2-Bromo-3-methylphenyl)imino]methyl}benzene-1,2-diol: crystal structure and Hirshfeld surface analysis

In the title Schiff base derivative carrying a 2-bromo-3-methyl­phenyl group, the conformation about the C=N bond is E. In the crystal, O—H⋯O hydrogen-bond inter­actions consolidate the crystal packing. A Hirshfeld surface analysis and fingerprint plots were used to further investigate the inter­molecular inter­actions in the solid state.

The title compound, C₁₄H₁₂BrNO₂, was synthesized by the condensation reaction of 2,3-di­hydroxy­benzaldehyde and 2-bromo-3-methyl­aniline. It crystallizes in the centrosymmetric triclinic space group P. The configuration about the C=N bond is E. The dihedral angle between the planes of the 5-(2-bromo-3-methyl­phenyl ring and the catechol ring is 2.80 (17)°. In the crystal, O—H⋯O hydrogen-bond inter­actions consolidate the crystal packing.
