title: Dimethyl 2-[2-(2,4,6-tri-chloro-phen-yl)hydrazin-1-yl-idene]butane-dioate.
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 intra-molecular N-H⋯O hydrogen bond links the N-H group of the hydrazine to one of the meth-oxy groups of the butane-dioate moiety. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and π-π inter-actions are also observed [centroid-centroid separation = 3.535 (1) Å].
