title: Crystal structure of (E)-N'-benzyl-idene-1-methyl-4-nitro-1H-pyrrole-2-carbohydrazide.
abstract: In the title compound, C13H12N4O3, the dihedral angle between the planes of the pyrrole and benzene rings is 7.47 (1)°. In the crystal, mol-ecules are arranged in sheets lying parallel to (101). Neighbouring sheets are linked by N-H⋯O hydrogen bonds, weak π-π [centroid-centroid distance between the pyrrole rings = 3.765 (11) Å] and C-H⋯π inter-actions, forming a three-dimensional structure.
