Abstract:
The title mol-ecule, 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 intra-molecular O-H⋯N hydrogen bond. In the crystal, N-H⋯O hydrogen bonds form chains of mol-ecules extending along the c-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.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
