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].
