N'-[(E)-1-(4-Chloro-phen-yl)ethyl-idene]-2-[4-(2-methyl-prop-yl)phen-yl]propano-hydrazide.

The asymmetric unit of the title compound, C(21)H(25)ClN(2)O, contains four crystallographically independent mol-ecules, which differ mainly in the orientation of the isobutyl groups. The benzene rings are almost orthogonal to each other, forming dihedral angles of 87.40 (6), 88.69 (6), 84.88 (6) and 85.12 (6)° in the four mol-ecules. The crystal structure is stabilized by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, together with C-H⋯π inter-actions.
