Deskripsi
The asymmetric unit of the title cystosinium salt derivative, 2C4H6N3O+·C4H4O62−·H2O, contains two cytosinium cations, one tartaric acid anion and a water molecule. The two cytosinium cations are almost planar (r.m.s. deviations of the fitted atoms are 0.0151 and 0.0213 Å). The crystal structure features C—H...O, N—H...O and O—H...O interactions. Further C—O...π and π–π interactions are observed along the ab plane, contributing to the crystal stability.
