Crystal structure and Hirshfeld surface analysis of (3aSR,6RS,6aSR,7RS,11 bSR,11cRS)-2,2-dibenzyl2,3,6a,11c-tetrahydro-1H,6H,7H-3a,6:7,11 b-diepoxydi benzo[de,h] isoqui noli n-2-ium trifluoromethanesulfonate

In the cation of the title salt, C30H28NO2+-CF303S-, the four tetrahydrofuran rings adopt envelope conformations. In the crystal, pairs of cations are linked by dimeric C H...O hydrogen bonds, forming two R3:(6) ring motifs parallel to the (001) plane. The cations and anions are connected by further C H...O hydrogen bonds, forming a three-dimensional network structure. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H...H (47.6%), C...H/H...C (20.6%), O...H/H...O (18.0%) and F...H/H...F (9.9%) interactions.

Automated summary

In the cation of the title salt, the four tetrahydrofuran rings adopt envelope conformations are linked by dimeric C H...O hydrogen bonds, forming a three-dimensional network structure with the anions. The crystal packing is mainly contributed by H...H, C...H/H...C, O...H/H...O, and F...H/H...F interactions, according to Hirshfeld surface analysis.
