Abstract
The Zn(II) complexes: [Zn(Hbimtz)2Cl2]·H2O, [Zn2(Hbimtz)4Cl4]·H2O, and {[Zn2(H2O)4(SO4)2(Hbimtz)2]·(H2O)2.5}n, where Hbimtz = 1-[(1H-benzimidazole-2-yl)methyl]-1,2,3,4-tetrazole, have been synthesised and their structures determined. The mononuclear complexes have four–coordinated Zn(II) centres with two benzimidazole N atoms from Hbimtz and two terminal Cl atoms, while the Zn(II) centre of the dinuclear complex is ligated by N atoms of Hbimtz and O atoms of sulfate and water molecules in distorted octahedral geometry. The thermal stability and luminescent properties of the three complexes are also discussed.
