Abstract

The title compound, C19H17Cl3N2O3, has been prepared in a cyclo-condensation reaction between 2,3,5-tri-chloro-benzaldehye and 4-acetyl-2-methyl-1H-imidazole. The cyclo-hexenone ring adopts an envelope conformation with the C atom substituted by the tri-chloro-phenyl ring as the flap. The mutually trans ester and aryl substituents both occupy equatorial sites. In the crystal, a combination of N-H⋯O and C-H⋯N hydrogen bonds links the mol-ecules into ribbons of edge-fused centrosymmetric rings, which enclose R 2 (2)(14) and R 4 (4)(16) alternate ring motifs, propagating along the b-axis direction.

Keywords: crystal structure; cyclo­condensation reaction; hydrogen bonding; mol­ecular conformation; mol­ecular stereochemistry
