Abstract:
The title compound, C16H11BrN2, is a Schiff base formed through the condensation reaction of 2-quinoline-carboxaldehyde with 4-bromo-aniline. The C=N bond length of 1.282 (2) Å is consistent with its double-bond character. The imine linkage adopts the E configuration, as indicated by the N-C-C-N torsion angle of 174.27 (14)°. This value also demonstrates that the quinoline ring and imine group are arranged in an almost coplanar manner. In contrast, the 4-bromo-phenyl ring is significantly twisted relative to the imine-quinoline plane, as indicated by the C-N-C-C torsion angle of approximately 46.8 (2)°. Inter-molecular C-H⋯π inter-actions between quinolinyl and bromo-phenyl rings form a three-dimensional supra-molecular network in the crystal packing.
