title: 2,2,6,6-Tetramethyl-4-oxopiperidinium nitrate.
abstract: In the title compound, C(9)H(18)NO(+).NO(3)(-), the piperidinium ring adopts a slightly deformed chair conformation and the nitrate anion is disordered. The ions are arranged in hydrogen-bonded chains parallel to [001], in which the cations alternate with the anions. The intrachain hydrogen bonds are bifurcated and link the O atoms of the anions to the N atoms of the cations.
