Abstract

The title compound, C21H17N7O4, is in an 'extended' conformation aided by an intra-molecular N-H⋯O hydrogen bond. The pyrazole ring makes dihedral angles of 29.17 (6), 65.47 (4) and 9.91 (7)°, respectively, with the phenyl, pyrrole and benzene rings. In the crystal, mol-ecules are connected by pairs of N-H⋯O and C-H⋯O hydrogen bonds, forming inversion dimers which associate into ribbons running along the b axis through complementary C-H⋯O inter-actions.

(E)-4-{[2-(2,4-二硝基苯基)肼-1-基-二硝基]甲基}-3-甲基-1-苯基-5-(1h -吡咯-1-基)- 1h -吡唑的晶体结构。

标题化合物c21h17n704在分子内N-H⋯O氢键的帮助下处于“扩展”构象。吡唑环与苯环、吡咯环和苯环分别成29.17(6)、65.47(4)和9.91(7)°的二面角。在晶体中，分子由一对对N-H⋯O和C-H⋯O氢键连接，形成倒置二聚体，通过互补的C-H⋯O相互作用结合成沿b轴运行的带状。
