3-Acetyl-2-fluoro-6H-benzo[c]chromen-6-one

The title compound, C15H9FO3, was obtained in a one-pot synthesis by Suzuki-Miyaura cross-coupling and nucleophilic substitution reaction of 4′-chloro-2′,5′-difluoroacetophenone with o-(methoxycarbonyl)phenylboronic acid. The asymmetric unit contains two crystallographically independent molecules related by a non-crystallographic inversion centre. There are face-to-face stacking interactions between the aromatic rings of the benzoate and acetophenone units of the symmetry-independent molecules [centroid-centroid distances = 3.870(3) and 3.986(3)Å]. In the crystal, molecules are further assembled via stacking interactions along the a-axis direction. One of the molecules interacts with its inversion equivalent [centroid-centroid distance between the aromatic rings of the benzoate and acetophenone units = 3.932(3)Å], and the other interacts with its twofold axis equivalent [centroid-centroid distance between the aromatic rings of acetophenone units = 3.634(3)Å].
