Bis(2-amino-pyrimidine-κN)aqua-(nitrato-κO)(nitrato-κO,O')zinc(II).

The water-coordinated Zn atom in the title monoaqua zinc nitrate adduct of 2-amino-pyrimidine, [Zn(NO(3))(2)(C(4)H(5)N(3))(2)(H(2)O)], is bonded to a monodentate nitrate ion and is chelated by the other nitrate ion. The heterocyclic ligands coordinate through ring N-donor sites. The coordination geometry about the Zn(II) atom is a distorted octa-hedron. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, adjacent adduct mol-ecules are linked by O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds into a layer motif parallel to (001).
