In the title compound, C12H10O4, the dihedral angle between the coumarin ring system [maximum deviation = 0.033 (8) Å] and the propionate side chain is 78.48 (8)°. In the crystal, weak C—H...O hydrogen bonds generate inversion dimers and and C—H...π and π–π interactions link the dimers into a three-dimensional network. A quantum chemical calculation is in good agreement with the observed structure.
