A 1:1 molecular complex of 4-aminocyclohexanol and (4-hydroxycyclohexyl)carbamic acid

The title molecular complex, 4-ammonio­cyclo­hexanol (4-hydroxy­cyclo­hexyl)­carbamate, C6H14NO+·C7H12NO3−, forms an ionic column with N—H⋯O, O—H⋯O and C—H⋯O interactions. There are two different cyclic supramol­ecular synthons of note. The crystal structures of ionic amino acids also have similar structural patterns.
