M. J. Todd and W. T. A. Harrison

Abstract: The title compound, 2C₇H₁₆N⁺·HAsO₄^2-·H₂O, contains a network of cycloheptylaminium cations, hydrogenarsenate anions and water molecules. The crystal packing involves N-HO [average HO = 1.86 Å, N-HO = 172° and NO = 2.756 (2) Å] and O-HO [average HO = 1.91 Å, O-HO = 168° and OO = 2.756 (2) Å] hydrogen bonds, resulting in a layered structure.
