2-Oxo-2H-chromen-7-yl pentanoate

Résumé

In the title compound, C14H14O4, the dihedral angle between the coumarin nucleus and the pentanoate 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, molecules are linked by C—H…..O hydrogen bonds into centrosymmetric dimers with an R2 2 (8) graph-set motif, and the cohesion of the crystal is also supported by - interactions with a centroid–centroid distance of 3.9342 (8) Å . A Hirshfeld surface analysis revealed that 44.6% of the intermolecular interactions are from H….H contacts, 28.2% are from …..O/O…..H contacts and 16.3% are from H…..C/C.….H.
