3-(3-Chlorobenzyl)-1H-isochromen-1-one

The asymmetric unit of the title compound, C16H11ClO2, a chemically synthesized isocoumarin, contains three independent molecules. The benzopyran and benzene rings are approximately perpendicular to each other, forming dihedral angles ranging from 83.08 (14) to 87.43 (11)°. In the crystal structure, molecules are linked by intermolecular C—H⋯O hydrogen-bonding interactions, forming chains running parallel to the a axis.
