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.
在标题化合物C₂₄H₂₀BrN₃O₄S中,中心苯环与吡唑啉酮环、溴苯环和末端苯环分别形成24.55 (8)°、49.52 (12)°和59.65 (7)°的二面角。堆积通过形成与反演相关的二聚体的弱非经典分子间C—H⋯O=C氢键得以稳定。
