title: Cyclo-octanaminium hydrogen succinate monohydrate.
abstract: In the title hydrated salt, C(8)H(18)N(+)·C(4)H(5)O(4) (-)·H(2)O, the cyclo-octyl- ring of the cation is disordered over two positions in a 0.833 (3):0.167 (3) ratio. The structure contains various O-H.·O and N-H⋯O inter-actions, forming a hydrogen-bonded layer of mol-ecules perpendicular to the c axis. In each layer, the ammonium cation hydrogen bonds to two hydrogen succinate anions and one water mol-ecule. Each hydrogen succinate anion hydrogen bonds to neighbouring anions, forming a chain of mol-ecules along the b axis. In addition, each hydrogen succinate anion hydrogen bonds to two water mol-ecules and the ammonium cation.
