Abstract

The bicyclic imidazo[1,2-a]pyridine core in the molecule of the title compound, C10H7F3N2O, is planar within 0.004 (1) angstrom. In the crystal, the molecules are linked by pairs of C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds, forming strips. These strips are connected by the F center dot center dot center dot F contacts into layers, which are further joined by pi-pi stacking interactions. The Hirshfeld surface analysis and fingerprint plots reveal that molecular packing is governed by F center dot center dot center dot H/H center dot center dot center dot F (31.6%), H center dot center dot center dot H (16.8%), C center dot center dot center dot H/H center dot center dot center dot C (13.8%) and O center dot center dot center dot H/H center dot center dot center dot O (8.5%) contacts.
