Abstract

In the meta-terphenyl fragment of the title mol-ecule, C(29)H(22)F(2)O(2), the two fluoro-phenyl rings are twisted from the central benzene ring by 46.72 (6) and 41.70 (6)°, respectively. In the crystal, weak C-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules into layers parallel to the ab plane. The crystal packing exhibits π-π inter-actions, the shortest distance between the centroids of aromatic rings being 3.6364 (7) Å.
