Bis[(1S,1′S)-1,1′-(4-amino-4H-1,2,4-triazole-3,5-di­yl)diethanol-κN¹]bis­(nitrato-κO)zinc

In the title homochiral mononuclear compound, [Zn(NO₃)₂(C₆H₁₂N₄O₂)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 NO₃⁻ anions, adopting a distorted tetra­hedral coordination geometry. The compound is enanti­omerically pure and corresponds to the S diastereoisomer, with the optical activity originating from the chiral ligand. In the crystal, mol­ecules are connected into three-dimensional supra­molecular networks through O—H...O, O—H...N and N—H...O hydrogen bonds.
