title: 2,2,2-Trifluoro-N-(4-methyl-2-oxo-2H-chromen-7-yl)acetamide.
abstract: In the title mol-ecule, C(12)H(8)F(3)NO(3), the trifluoro-methyl 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 mol-ecules related by translation into chains along the c axis. The crystal packing exhibits π-π inter-actions between the pyran rings of neighboring mol-ecules [centroid-centroid distance = 3.462 (4) Å] and short C⋯O contacts of 3.149 (4) Å.
