Abstract: In the title compound, C12H11Cl3N2O4, the dihedral angle between the aromatic ring and the hydrazine (NH-N=C) grouping is 52.2 (3)°. The butanedioate groups exhibit planar conformations. An intra­molecular N-H...O hydrogen bond links the N-H group of the hydrazine to one of the meth­oxy groups of the butane­dioate moiety. In the crystal, mol­ecules are linked by C-H...O hydrogen bonds and [pi]-[pi] inter­actions are also observed [centroid-centroid separation = 3.535 (1) Å].
