title: Bis(4-amino-3,5-di-2-pyridyl-1,2,4-triazole-κN,N)diaqua-zinc(II) dinitrate.
abstract: The asymmetric unit of the title compound, [Zn(C(12)H(10)N(6))(2)(H(2)O)(2)](NO(3))(2), contains one-half of the complex molecule and one NO(3) (-) anion. The Zn(II) ion displays a distorted tetra-gonal-pyramidal geometry with four N atoms from two chelating 4-amino-3,5-di-2-pyridyl-1,2,4-triazole (2-bpt) lig-ands in the basal plane and one water mol-ecule occupying the apical site. Another water mol-ecule at the opposite of the apical site has a weak inter-action with the Zn(II) ion [Zn-O = 2.852 (5) Å]. The Zn(II) ion and the two water mol-ecules lie on a twofold rotation axis. An extensive system of hydrogen bonds involving the NH(2) groups of the 2-bpt ligands, water mol-ecules and nitrate anions links all residues into a three-dimensional network.
