Synthesis, Structure and Photoluminescent Properties of Zn(II) -Complex with 2,4,6-tris-(benzimidazolyl-2-yl)pyridine Ligand

Abstract:

This hydrothermal reaction of tridentate rigid 2,4,6-tris-(benzimidazolyl-2-yl)pyridine (pytbzim) ligand, linear bridging 4,4′-bipyridine (4,4′-bpy) ligand and Zn(II) salts in acetonitrile and water mixed solvents generates a new complex {[Zn₃I₆(4,4′-bpy)(pytbzim)₃].(H₂O)₂.(CH₃CN)}_n. The asymmetry unit of complex contains a [ZnI₂(pytbzim)] and a {[Zn₂I₂(4,4′-bpy)₂(pytbzim)₂] units, which further construct into a three-dimensional supramolecular networks through p-p stacking interaction and rich hydrogen bonds between units and solvents. The solid state photoluminescence studies reveal good fluorescent properties of the pytbzim ligand and Zn(II)-complex at room temperature.
