In the title compound, CHBrNO, the pyridine ring is essentially planar [maximum deviation = 0.024 (4) Å for the N atom] and makes dihedral angles of 74.6 (2) and 65.8 (2)°, respectively, with the phenyl and bromo-phenyl rings, which subtend a dihedral angle of 63.1 (2)°. In the crystal, mol-ecules are connected along the -axis direction C-Br⋯π inter-actions, generating zigzag chains parallel to the (010) plane. C-H⋯N and C-H⋯O hydrogen-bonding inter-actions further connect the mol-ecules, forming a three-dimensional network and reinforcing the mol-ecular packing. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (36.2%), C⋯H/H⋯C (21.6%), N⋯H/H⋯N (12.2%), and Br⋯H/H⋯Br (10.8%) inter-actions.
