Abstract
In the title compound, C14H9Cl2N3O4·C3H7NO, the hydrazone molecule adopts anEconformation 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 molecule is stabilized by the intramolecular 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 dimethylformamide solvent molecule is connected to the hydrazone NH groupviaan N—H...O hydrogen bond. In the crystal, non-classical C—H...O and C—H...Cl hydrogen bonds link the molecules into chains along [322]. A supramolecular 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] interactions.
