2,2,2-Trifluoro-N-(4-methyl-2-oxo-2H-chromen-7-yl)acetamide

Abstract

In the title molecule, C12H8F3NO3, the trifluoromethyl group is rotationally disordered over three orientations in a 0.5:0.3:0.2 ratio. In the crystal, N—H...O hydrogen bonds link the molecules related by translation into chains along thecaxis. The crystal packing exhibits π–π interactions between the pyran rings of neighboring molecules [centroid–centroid distance = 3.462 (4) Å] and short C...O contacts of 3.149 (4) Å.
