[1-(Carboxymethyl)Cyclohexyl]Methanaminium Dihydrogen Phosphate

Abstract

In the title salt, C<inf>9</inf>H<inf>18</inf>NO<inf>2</inf> +·H<inf>2</inf>PO<inf>4</inf> -, the Cyclohexane ring is puckered, the total puckering amplitude Q T being 0.555 (4) Å, and an intramolecular N - H⋯O hydrogen bond generates an S(7) ring. In the crystal structure, intermolecular N - H⋯O and O - H⋯O hydrogen bonds lead to R 2 2(14), R 3 3(8) and R 4 2(8) rings, generating a two-dimensional layer. © 2010.
