description

The title diepoxyphenalene derivative, C17H18O6, comprises a fused cyclic system containing four five-membered rings (two dihydrofuran and two tetrahydrofuran) and one six-membered ring (cyclohexane). The five-membered dihydrofuran and tetrahydrofuran rings adopt envelope conformations, and the six-membered cyclohexane ring adopts a distorted chair conformation. Two methyl carboxylate groups occupy adjacent positions (2- and 3-) on a tetrahydrofuran ring. In the crystal, two pairs of C-H center dot center dot center dot O hydrogen bonds link the molecules to form inversion dimers, enclosing two R-2(2)(6) ring motifs, that stack along the a-axis direction and are arranged in layers parallel to the bc plane.
