In the title compound, C(22)H(18)N(4)O(2)S, the seven-membered ring generated by an intra-molecular N-H⋯O hydrogen bond adopts an envelope conformation in both of the two independent mol-ecules in the asymmetric unit. In the crystal, mol-ecules are linked into C(9) chains along [100] by N-H⋯O hydrogen bonds. The mol-ecules are also weakly linked by C-H⋯O and C-H⋯N inter-actions, forming dimers with edge-connected R(2) (2)(9) rings. The dimers are inter-linked by further weak C-H⋯N hydrogen bonds into chains along [010].
在标题化合物C₂₂H₁₈N₄O₂S中,由分子内N-H⋯O氢键形成的七元环在不对称单元中的两个独立分子中均呈信封构象。在晶体中,分子通过N-H⋯O氢键沿[100]方向连接成C(9)链。分子还通过C-H⋯O和C-H⋯N相互作用微弱连接,形成具有边连接R₂²(9)环的二聚体。这些二聚体通过进一步的弱C-H⋯N氢键沿[010]方向相互连接成链。
