Crystal structure and Hirshfeld surface analysis of (3a SR,6 RS,6a SR,7 RS,11b SR,11c RS)-2,2-dibenzyl-2,3,6a,11c-tetra-hydro-1 H,6 H,7 H-3a,6:7,11b-di-epoxy-dibenzo[ de, h]isoquinolin-2-ium tri-fluoro-methane-sulfonate

Abstract

In the cation of the title salt, C30H28NO2 + CF3O3S , the four tetrahydrofuran rings adopt envelope conformations. In the crystal, pairs of cations are linked by dimeric C—H O hydrogen bonds, forming two R2 2(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.
