Crystal structure and Hirshfeld surface analysis of dimethyl 2-oxo-4-(pyridin-2-yl)-6-(thio-phen-2-yl)cyclo-hex-3-ene-1,3-di-carboxyl-ate.

In the title compound, C(19)H(17)NO(5)S, the cyclo-hexene ring adopts nearly an envelope conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming a three-dimensional network. In addition, C-H⋯π inter-actions connect the mol-ecules 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%) inter-actions are the most significant contributors to the crystal packing.
