title: 2-Oxo-2H-chromen-4-yl propionate.
abstract: In the title compound, C12H10O4, the atoms of the 2-oxo-2H-chromene ring system and the non-H atoms of the 4-substituent all lie on a crystallographic mirror plane. The mol-ecular structure exhibits an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules form R 3 (2)(12) trimeric units via C-H⋯O inter-actions which propagate into layers parallel to the ac plane. These layers are linked by weak C-H⋯O inter-actions along the [010] direction, generating a three-dimensional network.
