In the title compound, [Cd(NO3)2(C5H7N3O)2], the CdII atom is eight-coordinated by two amine N atoms and two O atoms from two zwitterionic, biodentate 2-amino-6-methylpyrimidin-1-ium-4-olate ligands and by four O atoms from two nitrate groups. Intramolecular N—HO hydrogen bonds occur. The crystal packing is stabilized by intermolecular N—HO and C—HO hydrogen bonds, two of which are bifurcated, between the nitrate anions and the organic groups.
