N'-[(E)-4-Chloro-benzyl-idene]-2-(4-isobutyl-phen-yl)propanohydrazide.

ABSTRACT: The asymmetric unit of title compound, C(20)H(23)ClN(2)O, consists of two crystallographically independent mol-ecules (A and B) in which the orientations of the 4-isobutyl-phenyl units are different. The isobutyl group of mol-ecule B is disordered over two positions with occupancies of 0.850 (5) and 0.150 (5). The dihedral angle between the two benzene rings is 88.70 (9)° in mol-ecule A and 89.38 (9)° in mol-ecule B. The independent mol-ecules are linked together into chains along [100] by N-H⋯O and C-H⋯O hydrogen bonds, and by C-H⋯π inter-actions. In the chain, N-H⋯O and C-H⋯O hydrogen bonds generate R(2) (1)(6) ring motifs. In addition, C-H⋯N hydrogen bonds are observed. The presence of pseudosymmetry in the structure suggests the higher symmetry space group Pbca but attempts to refine t
