✦ Synopsis

The asymmetric unit of the title compound, C 15 H 15 BrN 4 OÁ-H 2 O, consists of a roughly planar Schiff base molecule and a solvent water molecule. The Schiff base molecule displays a trans configuration with respect to the C N double bond. The dihedral angle between the benzene and pyridine rings is 4.6 (2) . In the crystal structure, molecules are linked through intermolecular O-HÁ Á ÁO and O-HÁ Á ÁN hydrogen bonds.
