Cytosinium hydrogen selenite

Abstract

In the crystal structure of the title salt, C4H6N3O+·HSeO3−, systematic name 6-amino-2-methylidene-2,3-dihydropyrimidin-1-ium hydrogen selenite, the hydrogenselenite anions and the cytosinium cations are linked via N—H...O, N—H...Se, O—H...O, O—H··Se and C—H...O hydrogen bonds, forming a three-dimensional framework.
