Crystal structure, Hirshfeld surface analysis and frontier mol-ecular orbital analysis of ()-4-bromo-'-(2,3-di-chloro-benzyl-idene)benzohydrazide.

The title Schiff base compound, CHBrClNO, displays a or configuration with respect to the C=N bond, with a dihedral angle 15.7 (2)° formed between the benzene rings. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming chains along [001] which enclose (6) loops. The inter-molecular inter-actions were investigated by Hirshfeld surfaces analysis and two-dimensional fingerprint plots. The DFT-B3LYP/6-311 G++(d,p) method was used to determine the HOMO-LUMO energy levels.
