Crystal structure and Hirshfeld surface analysis of 1-(furan-2-yl)-2-(thio-phene-2-carbon-yl)-3-(thio-phen-2-yl)-2,3,3a,8a-tetra-hydro-cyclo-penta-[a]inden-8(1H)-one.

In the title compound, C25H18O3S2, the terminal cyclo-pentane ring adopts an envelope conformation. In the racemic crystal, pairs of enanti-omers are linked by C-H⋯O hydrogen inter-actions, forming R 2 2(10) ring motifs. The (1R,2S,3S,3aR,8aS) and (1S,2R,3R,3aS,8aR) enanti-omers are also connected by further C-H⋯O inter-actions, forming ribbons propagating along the a-axis direction. In addition, C-H⋯π inter-actions between these ribbons form layers parallel to the (001) plane. Crystal cohesion is ensured by van der Waals inter-actions between layers. The furan ring and the two thio-phene rings are disordered by a 180° rotation, with ratios of 0.728 (15):0.272 (15), 0.972 (3):0.028 (3) and 0.791 (3):0.209 (3), respectively. According to Hirshfeld surface analysis, the most important contributions for the crystal packing are H⋯H (52.8%), C⋯H/H⋯C (26.1%) and O⋯H/H⋯O (14.8%) inter-actions.
