Crystal structure and Hirshfeld surface analysis of ethyl 2-({5-acetyl-3-cyano-6-methyl-4-[(E)-2-phenyl-ethen-yl]pyridin-2-yl}sulfan-yl)acetate.

In the title molecule, C21H20N2O3S, the styryl and ester substituents are displaced to opposite sides of the plane of the pyridine ring. In the crystal, C—H⋯O hydrogen bonds form chains extending parallel to the a-axis direction, which pack with partial intercalation of the styryl and ester substituents. A Hirshfeld surface analysis indicates that the most significant contributions to the crystal packing are from H⋯H (43.6%), C⋯H/H⋯C (15.6%), O⋯H/H⋯O (14.9%) and N⋯H/H⋯N (11.2%) contacts.
