The crystal structure of the title compound, C7H14NO2 +· Cl-, was reported previously [Chacko, Srinivasan & Zand (1975). J. Cryst. Mol. Struct. 5, 353-357] from Weissenberg photographic data with R = 0.113. It has now been redetermined, providing a significant increase in the precision of the derived geometric parameters, viz. mean (C - C) = 0.003 Å in the present work compared with 0.021 Å for the previous work. The complete cation is generated by crystallographic mirrror symmetry, with three C atoms, two O atoms and the N atom lying on the reflecting plane; the chloride anion also has m site symmetry. The crystal structure is established by a two-dimensional network of O - H⋯Cl and N - H⋯Cl hydrogen bonds, generating C 1 2(4) and C 1 2(7) chains, and R 2 4(8) and R 2 4(14) rings.
