Özet
In the title compound, C20H19NO5, the central six-membered ring has a slightly distorted half-chair conformation, with puckering parameters of Q(T) = 0.3387 (11) angstrom, theta = 49.11 (19)degrees and phi = 167.3 (2)degrees. The conformation of the fused pyrrolidine ring is that of an envelope. Molecules are connected by intermolecular C-H center dot center dot center dot O hydrogen bonds, C-H center dot center dot center dot pi interactions and pi-pi stacking interactions [centroid-to-centroid distance = 3.9536 (11) angstrom, with a slippage of 2.047 angstrom], forming a three-dimensional network. The most important contributions to the surface contacts are from H center dot center dot center dot H (46.3%), O center dot center dot center dot H/H center dot center dot center dot O (31.5%) and C center dot center dot center dot H/H center dot center dot center dot C (17.3%) interactions, as concluded from a Hirshfeld surface analysis.
