2-Oxo-2H-chromen-7-yl penta-noate.

In the title compound, C14H14O4, the dihedral angle between the coumarin nucleus and the penta-noate moiety is 62.20 (7)°. The coumarin moiety is planar as usual, with a maximum deviation from the least-squares plane of 0.081 (2) Å. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into centrosymmetric dimers with an R 2 2(8) graph-set motif, and the cohesion of the crystal is also supported by π-π inter-actions with a centroid-centroid distance of 3.9342 (8) Å. A Hirshfeld surface analysis revealed that 44.6% of the inter-molecular inter-actions are from H⋯H contacts, 28.2% are from ⋯O/O⋯H contacts and 16.3% are from H⋯C/C⋯H.
