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

In the title mol­ecule, C(12)H(8)F(3)NO(3), 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 the c axis. The crystal packing exhibits π–π inter­actio...

Descripción
Sumario:In the title mol­ecule, C(12)H(8)F(3)NO(3), 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 the c axis. 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.
