Abstract: 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 [pi]-[pi] [centroid-centroid phen­yl-phenyl and pyrrol­yl-pyrrolyl distances of 3.7816 (3) and 3.8946 (2) Å, respectively] inter­actions occur between neighbouring sheets.
