| Popis: | The title compound, C21H12Br2F13NO·2CH3OH, was obtained by condensation of 4-methyl-1-(1H,1H,2H,2H-perfluorooctyl)pyridinium iodide and 3,5-dibromo-4-hydroxybenzaldehyde, followed by deprotonation. It crystallizes as a methanol disolvate and exhibits short O—H...O hydrogen bonds and a disordered perfluoroalkyl chain [occupancy ratio 0.538 (7):0.462 (7)]. Significant π–π stacking interactions are observed between the benzene and pyridine rings of neighbouring molecules along the b-axis direction. |
