Crystal structure and solid-state properties of discrete hexa cationic trinuclear zinc triazole cluster



A linear trinuclear cluster of the type [{Zn3(HTrz)6(H2O)6}6+(NO\(_{\mathrm {3}}^{\mathrm {-}}\))6(H2O)] (ZnT) has been synthesized by one-pot reaction between 1,2,4-triazole and Zn(NO3).6H2O. Molecule consists of three Zn2++ ions linearly connected by 1,2,4-triazole with tri-fold symmetry. The coordination geometry around the zinc centre is octahedral with zinc-zinc separation of 3.810 Å. The coordination environment of central Zn2++ ion is satisfied by nitrogen atoms of six 1,2,4-triazoles, while the geometry of terminal Zn2++ ions is fulfilled by nitrogen atoms of three 1,2,4-triazoles and three water molecules. The thermal and absorption properties of ZnThave been reported for the first time.
