Crystal structure and Hirshfeld surface analysis of (±)-'-(2-hy-droxy-3-meth-oxy-benzyl-idene)-2-(4-iso-butyl-phen-yl)propionohydrazide.

The title mol-ecule, CHNO, adopts a V-shaped conformation and is chiral at the C atom with methyl group attached at the common cut of the edges of the V-conformation and crystallizes as a racemate. It also contains an intra-molecular O-H⋯N hydrogen bond. In the crystal, N-H⋯O hydrogen bonds form chains of mol-ecules extending along the -axis direction, together with normal van der Waals contacts. The roles of the various inter-molecular inter-actions were clarified by Hirshfeld surface analysis, which reveals that the most important contributions to the crystal packing are from H⋯H (62.6%), C⋯H/H⋯C (15.8%) and O⋯H/H⋯O (15.3%) contacts.
