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].

Among the large number of compounds, 4-amino-1,5-dimethyl-2-phenylpyrazol-3-one forms a variety of Schiff bases with aldehydes, and the synthesis and crystal structures of some of them, such as (E)-4-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylimino) methyl]-phenyl 4-chlorobenzoate (Han et al, 2007) has been reported
Summary
R factor = 0.044; wR factor = 0.107; data-to-parameter ratio = 13.9. 58.37 (13) , respectively, with the pyrazolone ring, the bromobenzene ring and the terminal phenyl ring. 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].
