Abstract

The title compound, 1-(7,8-dimethyl-2-oxo-2H-chromen-4-ylmethyl)-pyrrolidine-2,5-dione, crystallizes in the triclinic system, with a space group P1. The unit-cell parameters: a = 7.309(2)Å, b = 9.677(3)Å, c = 9.746(3)Å, α = 91.096(5)°, β = 100.682(5)°, γ = 102.191(5)°, Z = 2. The pyrrolidine ring is planar, and rotated by 82.36° with respect to the coumarin moiety. The packing of layers is stabilized by C-H…O, C-H…π hydrogen bonds and the π-π stacking interaction.
