title: (E)-3-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino-meth-yl]phenyl 4-bromo-benzene-sulfonate.
abstract: In the title compound, C(24)H(20)BrN(3)O(4)S, the central benzene ring makes dihedral angles of 24.55 (8), 49.52 (12) and 59.65 (7)°, respectively, with the pyrazolone ring, the bromo-benzene ring and the terminal phenyl ring. The packing is stabilized by weak non-classical inter-molecular C-H⋯O=C hydrogen bonds that form inversion-related dimers.
