Abstract: The title compound, C13H19NO8, is based on a tetra-substituted pyrrolidine ring, which has a twisted conformation about the central C—C bond; the Cm—Ca—Ca—Cme torsion angle is 38.26 (15)° [m = methyl­carboxyl­ate, a = acet­yloxy and me = methyl­ene]. While the N-bound ethyl­carboxyl­ate group occupies an equatorial position, the remaining substituents occupy axial positions. In the crystal, supra­molecular double-layers are formed by weak methyl- and methyl­ene-C—H⋯O(carbon­yl) inter­actions involving all four carbonyl-O atoms. The two-dimensional arrays stack along the c axis without directional inter­actions between them. The Hirshfeld surface is dominated by H⋯H (55.7%) and H⋯C/C⋯H (37.0%) contacts; H⋯H contacts are noted in the inter-double-layer region. The inter­action energy calculations point to the importance of the dispersion energy term in the stabilization of the crystal
