In the title dinuclear complex, [Zn2I4(C6H8N6)2], two ZnII atoms are bridged by two 1,2-bis(1,2,4-triazol-4-yl)ethane (btre) ligands, forming a centrosymmetric metallacycle. The coordination geometry of the ZnII ion is distorted tetrahedral with the coordination sphere formed by two N atoms from the triazole rings of two symmetry-related btre ligands and two iodide ligands.
