Crystal structure of N'-[(E)-3,5-di-chloro-2-hy-droxy-benzyl-idene]-4-nitro-benzo-hydrazide di-methyl-formamide monosolvate.

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?? [4.163?(3)?Å, 83.26?(9)°] and ?-? [centroid-centroid distance = 4.0395?(14)?Å] inter-actions.
