✦ Synopsis
In the title Schiff base, C 19 H 19 N 3 O 2 , the dihydropyrazole ring is essentially planar, with an r.m.s. deviation of 0.0289 A ˚for the fitted atoms. This ring makes dihedral angles of 41.8 (2) and 51.1 (3) with the phenyl and benzene rings, respectively. In the crystal structure, there is one intramolecular O-HÁ Á ÁN hydrogen bond.

The title compound, C 18 H 15 BrClN 3 O 2 , was obtained by reacting 3-bromo-5-chlorosalicylic aldehyde and 4-aminoantipyrine. The structure displays a trans configuration about the imine C N double bond. The N atom is also involved in an intramolecular O-HÁ Á ÁN hydrogen bond, which stabilizes the
