(E)-N′-(2-Chloro­benzyl­idene)-1-methyl-4-nitro-1H-pyrrole-2-carbohydrazide

In the title compound, C₁₃H₁₁ClN₄O₃, the phenyl and pyrrolyl ring are linked by an ac­yl–hydrazone (R₂C=N—N—CO—R) group, forming a slightly bent mol­ecule: the dihedral angle subtended by the the phenyl and pyrrolyl rings is 8.46 (12)°. In the crystal, the three-dimensional supra­molecular structure is assembled by N—H...O hydrogen bonding. Mol­ecular sheets are formed parallel to (101) in a herringbone arrangement by weak van der Waals inter­actions; weak π–π [centroid–centroid phen­yl–phenyl and pyrrol­yl–pyrrolyl distances of 3.7816 (3) and 3.8946 (2) Å, respectively] inter­actions occur between neighbouring sheets.
