Cyclo­octanaminium hydrogen succinate monohydrate

In the title hydrated salt, C(8)H(18)N(+)·C(4)H(5)O(4) (−)·H(2)O, the cyclo­octyl­ 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 inter­actions, forming a hydrogen-bonded layer of mol­ecules perpendicular to the c axis. In each layer, the ammonium cation hydrogen bonds to two hydrogen succinate anions and one water mol­ecule. Each hydrogen succinate anion hydrogen bonds to neighbouring anions, forming a chain of mol­ecules along the b axis. In addition, each hydrogen succinate anion hydrogen bonds to two water mol­ecules and the ammonium cation.
