摘要

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。

Crystal structure of (E)-4-{[2-(2,4-di-nitro-phen-yl)hydrazin-1-yl-idene]meth-yl}-3-methyl-1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazole.

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.

期刊介绍： Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
