Add to ORKGR factor = 0.053; wR factor = 0.170; data-to-parameter ratio = 20.0. In the title compound, C17H13ClO3, the coumarin and phenoxy moieties are essentially co-planar, making a dihedral angle of 1.99 (7). The phenoxy moiety is oriented antiperiplanar with respect to the coumarin ring as indicated by the C—C—O—C angle of 179.97 (16). In the crystal, the sheet-like packing is stabilized by intermolecular C—H O and C—H Cl hydrogen bonds.
