    Crystal structure and Hirshfeld surface analysis of dimethyl (3aS,6R,6aS,7S)-2-(2,2,2-trifluoroacetyl)-2,3-dihydro-1H,6H,7H-3a,6:7,9a-diepoxybenzo[de]isoquinoline-3a1,6a-dicarboxylate

    The title molecule, C18H16F3NO7, comprises a fused cyclic system containing four five membered (two dihydrofuran and two tetrahydrofuran) rings and one six-membered (piperidine) ring. The five-membered dihydrofuran and tetrahydrofuran rings adopt envelope conformations, and the six-membered piperidine ring adopts a distorted chair conformation. Intramolecular OF interactions help to stabilize the conformational arrangement. In the crystal structure, molecules are linked by weak C—HO and C—HF hydrogen bonds, forming a three dimensional network. The Hirshfeld surface analysis confirms the dominant role of HH contacts in establishing the packing
