An intramolecular O—H O hydrogen bond occurs in the hydrogen maleate anion. The crystal packing is stabilized by intermolecular N—H O, N—H N and C—H O hydrogen bonds, giving rise to a nearly planar two-dimensional network parallel to (101)enCytosinium–hydrogen maleate–cytosine (1/1/1)Cytosinium–hydrogen maleate–cytosine (1/1/1)Article
