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.

Project description:In the title homochiral mononuclear compound, [Zn(NO(3))(2)(C(6)H(12)N(4)O(2))(2)], the Zn(II) atom is located on a twofold rotation axis and coordinated by two N atoms from two ligands and two O atoms from two NO(3) (-) anions, adopting a distorted tetra-hedral coordination geometry.

In the crystal, mol-ecules are connected into three-dimensional supra-molecular networks through O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds.

4-Amino-3,5-di-2-pyridyl-4H-1,2,4-triazole.

Project description:In the crystal structure of the title compound, C(12)H(10)N(6), the mol-ecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intra-molecular N-H⋯N inter-actions form six-membered closed rings. The crystal packing also shows weak C-H⋯π and C-H⋯N inter-actions.
