Abstract

In the title compound, C25H22BrN3O5S, the central benzene ring makes dihedral angles of 32.02 (14), 37.49 (18) and 80.52 (13)°, respectively, with the pyrazolone ring, the bromo­benzene ring and the terminal phenyl ring. This conformation features a short intramolecular C—H⋯O contact that generates an S(6) ring. In the crystal, inversion dimers linked by pairs of C—H⋯O=C hydrogen bonds occur.
