✦ Synopsis
The geometric parameters of the title compound, C 15 H 13 BrN 2 O 3 , are in the usual ranges. The C N double bond is trans configured. The C N-N-CO-group itself is planar, with an r.m.s. deviation of 0.044 A ˚, and makes a dihedral angle of 10.73 (19) with the hydroxyphenyl ring, but forms a dihedral angle of 67.90 (8) with the other aromatic ring. The crystal packing is stabilized by N-HÁ Á ÁO, O-HÁ Á ÁO and O-HÁ Á ÁN hydrogen bonds.

In the title compound, C~8~H~9~BrN~2~O~2~, the amide bond is in a __cis__ configuation. The N—N—C=O group is planar [torsion angle 0.6 (6)°] and forms a dihedral angle of 46.4 (2)° with the aromatic ring. The crystal packing is stabilized by two strong and one rather weak N—H...O hydrogen bonds.
The title Schiff base compound, C 13 H 10 BrN 3 O 2 , was derived from the condensation reaction of salicylaldehyde with 5bromonicotinohydrazide. The dihedral angle between the benzene ring and the pyridine ring is 13.2 (4) . In the crystal structure, molecules are linked through N-HÁ Á ÁO and C-HÁ
