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