4-Hydroxy-2,2,6,6-tetra­methyl­piperidinium trifluoro­acetate

The title compound, C(9)H(20)NO(+)·C(2)F(3)O(2) (−), 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....

Sumario:The title compound, C(9)H(20)NO(+)·C(2)F(3)O(2) (−), 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 CF(3) group is disordered over two positions with almost equal site occupancy factors.
