Abstract
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.
