P. Prabakaran et al., Intermolecular N-H center dot center dot center dot O hydrogen-bonding interactions in 5-fluorocytosinium salicylate, ACT CRYST E, 57, 2001, pp. o933-o936
The title compound, C4H5FN3O+.C7H5O3-, exists as a hydrogen-bonded heterodi
mer of 5-fluorocytosinium and salicylate ions which are connected through a
pair of nearly parallel specific N-H . . .O hydrogen bonds. The heterodime
r self-assembles via intermolecular N-H . . .O hydrogen bonds to form linea
r, as well as helical, hydrogen-bonded supramolecular chains that are inter
woven into a three-dimensional network structure.
