title: Supramolecular hydrogen-bonded networks in adeninium phenylacetate phenylacetic acid monohydrate and adeninium 3-carboxypropionate monohydrate.
abstract: In the title compounds, C(5)H(6)N(5)(+) x C(8)H(7)O(2)(-) x C(8)H(8)O(2) x H(2)O, (I), and C(5)H(6)N(5)(+) x C(4)H(3)O(4)(-) x H(2)O, (II), the adeninium cations form N-H...O hydrogen bonds with their anion counterparts and adeninium-adeninium self-association base pairs with the R(2)(2)(10) motif (Bernstein et al., 1995). A complete hydrogen-bonding motif analysis is presented. Conventional hydrogen bonds lead to layer structures in (I) and to two-dimensional infinite polymeric ribbons in (II). C-H...O interactions are found in both structures, while weak pi-pi stacking interactions are only observed in (I).
