title: Redetermination of 1-carboxy-cyclo-hexan-1-aminium chloride.
abstract: The crystal structure of the title compound, C(7)H(14)NO(2) (+)·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 σ(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.
