✦ Synopsis
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 Á ÁO intermolecular hydrogen bonds, forming chains running along the c axis.
