4-Hydroxy-2,2,6,6-tetramethylpiperidinium hydrogensulfate monohydrate

Abstract

In the title compound, C9H20NO+·HO4S−·H2O, the piperidinium ring adopts a chair conformation. Intermolecular O—H...O and N—H...O hydrogen bonds form an extensive three-dimensional network, which consolidates the crystal structure.
