Bottom Line: In the title compound, C14H9Cl2N3O4·C3H7NO, the hydrazone mol-ecule adopts an E conformation with respect to azomethine bond, and the dihedral angle between the two aromatic rings [8.96 (11)°] shows that the rings are almost co-planar.The azomethine and keto bond distances [1.269 (2) and 1.210 (2) Å, respectively] are very close to the formal C=N and C=O bond lengths.A supra-molecular three-dimensional architecture is created by weak C-Cl⋯π [4.163 (3) Å, 83.26 (9)°] and π-π [centroid-centroid distance = 4.0395 (14) Å] inter-actions.

ABSTRACT
In the title compound, C14H9Cl2N3O4·C3H7NO, the hydrazone mol-ecule adopts an E conformation with respect to azomethine bond, and the dihedral angle between the two aromatic rings [8.96 (11)°] shows that the rings are almost co-planar. The planar conformation of the mol-ecule is stabilized by the intra-molecular O-H⋯N hydrogen bond involving the OH group and azomethine N atom. The azomethine and keto bond distances [1.269 (2) and 1.210 (2) Å, respectively] are very close to the formal C=N and C=O bond lengths. The di-methyl-formamide solvent mol-ecule is connected to the hydrazone NH group via an N-H⋯O hydrogen bond. In the crystal, non-classical C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chains along [322]. A supra-molecular three-dimensional architecture is created by weak C-Cl⋯π [4.163 (3) Å, 83.26 (9)°] and π-π [centroid-centroid distance = 4.0395 (14) Å] inter-actions.
