Synthesis, structure and Hirshfeld surface analysis of 2-oxo-2H-chromen-4-yl pentanoate

Abstract

In the title compound, C14H14O4, the dihedral angle between the coumarin ring system (r.m.s deviation = 0.016 Å) and the pentanoate ring is 36.26 (8)°. A short intramolecular C—H...O contact of 2.40 Å is observed. Hirshfeld surface analysis reveals that 46.1% of the intermolecular interactions are from H...H contacts, 28.6% are from H...O/O...H contacts and 14.7% are from H...C/C...H.
