Crystal structure and Hirshfeld surface analysis of (±)-N′-(2-hydroxy-3-methoxybenzylidene)-2-(4-isobutylphenyl) propionohydrazide.

The title mol­ecule, C₂₁H₂₆N₂O₃, 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 intra­molecular O--H⋯N hydrogen bond. In the crystal, N--H⋯O hydrogen bonds form chains of mol­ecules extending along the c-axis direction, together with normal van der Waals contacts. The roles of the various inter­molecular inter­actions 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.
