✦ 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.

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 dihedr
