Abstract

The title compounds benzylammonium phenylacetate, C7H10N+center dot C8H7O2-(1), and its monohydrate, C7H10N+center dot C8H7O2- center dot H2O(2), can be obtained by evaporating methanolic solutions containing equimolar amounts of benzylamine and phenylacetic acid in the absence and presence of water, respectively. N-H center dot center dot center dot O hydrogen bonds in the crystal structure of 1 lead to the formation of hydrophilic channels running along the b-axis direction. The hydrogen-bonding system is best described by fused R-4(3)(10) ring patterns, often observed in ammonium carboxylate salts. In 2, the presence of the crystal water leads to the formation of a two-dimensional hydrogen-bonding network. The benzyl moieties in 1 and 2 form hydrophobic layers in the crystal structures with the aromatic rings adopting edge-to-face arrangements.
