Abstract :
The title compound, C15H14ClNO, was synthesized by condensation reaction of 2-hydroxy-5-methylbenzaldehyde and 3-chloro-4-methylaniline, and crystallizes in the monoclinic space group P21/c. The 3-chlorobenzene ring is inclined to the phenol ring by 9.38 (11)°. The configuration about the C=N bond is E and an intramolecular O—H⋯N hydrogen bond forms an S(6) ring motif. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the packing arrangement are from H⋯H (43.8%) and C⋯H/H⋯C (26.7%) interactions. The density functional theory (DFT) optimized structure at the B3LYP/ 6–311 G(d,p) level is compared with the experimentally determined molecular structure and the HOMO–LUMO energy gap is provided.
