The two hexane rings tend toward a distorted boat conformation, while the tetrahydrofuran and dihydrofuran rings adopt envelope conformations. The oxane ring is puckered. The crystal structure features C—H?O hydrogen bonds, which link the molecules into a three-dimensional network. According to a Hirshfeld surface study, H?H (60.3%) and O?H/H?O (35.3%) interactions are the most significant contributors to the crystal packing.eninfo:eu-repo/semantics/openAccess[Keywords Not Available]Crystal structure and Hirshfeld surface analysis of dieth­yl (3aS,3a1R,4S,5S,6R,6aS,7R,9aS)-3a1,5,6,6a-tetra­hydro-1H,3H,4H,7H-3a,6:7,9a-di­ep­oxy­benzo[de]isochromene-4,5-di­carboxyl­ateArticle8018387
