Abstract
The asymmetric unit of the title compound, C6H13N2O+·C8H7O2 −·0.5H2O, comprises two isonipecotamide cations, two phenylacetate anions and a water molecule of solvation. The hydrogen-bonding environments for both sets of ion pairs are essentially identical with the piperidinium and amide ‘ends’ of each cation involved in lateral heteromolecular hydrogen-bonded cyclic N—H⋯O associations [graph set R 2 2(11)] which incorporate a single carboxyl O-atom acceptor. These cyclic motifs enclose larger R 5 5(21) cyclic systems, forming sheet substructures which lie parallel to (101) and are linked across b by the single water molecule via water O—H⋯Oc (c = carboxylate) associations, giving a duplex-sheet structure.
