Deskripsi
The title compound, C9H20NO+·C2F3O2−, is an important intermediate in the synthesis of hindered light stabilizers. The piperidinium ring adopts a chair conformation with the hydroxyl group in an equatorial position. The crystal packing is stabilized by O—H...O and N—H...O hydrogen bonds. The CF3 group is disordered over two positions with almost equal site occupancy factors.
