Abstract: In the title compound, C20H19NO5, the central six-membered ring has a slightly distorted half-chair conformation, with puckering parameters of QT = 0.3387 (11) Å, θ = 49.11 (19)° and φ = 167.3 (2)°. The conformation of the fused pyrrolidine ring is that ... ...
Abstract | In the title compound, C20H19NO5, the central six-membered ring has a slightly distorted half-chair conformation, with puckering parameters of QT = 0.3387 (11) Å, θ = 49.11 (19)° and φ = 167.3 (2)°. The conformation of the fused pyrrolidine ring is that of an envelope. Molecules are connected by intermolecular C—H.O hydrogen bonds, C—H.π interactions and π–π stacking interactions [centroid-to-centroid distance = 3.9536 (11) Å, with a slippage of 2.047 Å], forming a three-dimensional network. The most important contributions to the surface contacts are from H.H (46.3%), O.H/H.O (31.5%) and C.H/H.C (17.3%) interactions, as concluded from a Hirshfeld surface analysis. |
