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.
