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

The title mol­ecule, C(21)H(26)N(2)O(3), 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.
