(E)-4-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)iminomethyl]phenyl 4-bromobenzenesulfonate

Abstract

In the title compound, C24H20BrN3O4S, the central benzene ring makes dihedral angles of 17.13 (13), 39.83 (13) and 58.37 (13)°, respectively, with the pyrazolone ring, the bromobenzene ring and the terminal phenyl ring. In the crystal structure, the packing is stabilized by a weak non-classical intermolecular C—H...O hydrogen bond which links the molecules into a chain propagating in [100].
