Crystal structure and Hirshfeld surface analysis of 2,2,2-trifluoro-1-(7-methylimidazo[1,2-a]pyridin-3-yl)ethan-1-one

Abstract

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