Cytosinium–hydrogen maleate–cytosine (1/1/1)
Abstract
The title organic salt, C4H6N3O+·C4H3O4−·C4H5N3O, was synthesized from cytosine base and maleic acid. 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).
