Abstract
In the title compound, C25H22BrN3O5S, the central benzene ring makes dihedral angles of 4.41 (10), 67.09 (9) and 62.05 (10)°, respectively, with the pyrazolone, bromobenzene and terminal phenyl rings. The dihedral angle between the pyrazolone and phenyl rings is 57.75 (11)°. In the crystal, two pairs of C—H⋯O hydrogen bonds link the molecules into inversion dimers. A weak intramolecular C—H⋯O hydrogen bonds is also observed.
