In the title compound, C<sub>16</sub>H<sub>9</sub>FO<sub>4</sub>, (I), the benzene ring is oriented at an acute angle of 59.03 (15)° relative to the coumarin plane (r.m.s deviation = 0.009 Å). This conformation of (I) is stabilized by an intra-molecular C-H⋯O hydrogen bond, which closes a five-membering ring. In the crystal, mol-ecules of (I) form infinite zigzag chains along the <i>b-</i>axis direction, linked by C-H⋯O hydrogen bonds. Furthermore, the crystal structure is supported by π-π stack ...[more]
