Crystal structure and Hirshfeld surface analysis of dimethyl 2-oxo-4-(pyridin-2-yl)-6-(thiophen-2-yl)cyclohex-3-ene-1,3-dicarboxylate

In the title compound, C19H17NO5S, the cyclohexene ring adopts nearly an envelope conformation. In the crystal, molecules are linked by C - H⋯O hydrogen bonds, forming a three-dimensional network. In addition, C - H⋯π interactions connect the molecules by forming layers parallel to the (010) plane. According to the Hirshfeld surface analysis, H⋯H (36.9%), O⋯H/H⋯O (31.0%), C⋯H/H⋯C (18.9%) and S⋯H/H⋯S (7.9%) interactions are the most significant contributors to the crystal packing. © 2024 International Union of Crystallography.
