Abstract: The nicotinamide (NA) molecules of the title compound, 2C₆H₆N₂O·C₂H₃F₃O, form centrosymmetric R²₂(8) hydrogen-bonded dimers via N-HO contacts. The asymmetric unit contains two molecules of NA and one trifluoroethanol molecule disordered over two sites of equal occupancy. The packing consists of alternating layers of nicotinamide dimers and disordered 2,2,2-trifluoroethanol molecules stacking in the c-axis direction. Intramolecular C-HO and intermolecular N-HN, O-HN, C-HN, C-HO and C-HF interactions are present.
