Synthesis,Structure and Properties of 2,5-Bis-(2′-benzimidazyl) Pyridine Ligand and Its Zinc(II) Complex

In this paper,2,5-bis-(2′-benzimidazyl)pyridine have been synthesized by microwave irradiation.Single crystals suitable for structural determinations of 2,5-bis-(2′-benzimidazyl)pyridine(1) and its zinc(Ⅱ) complex,[Zn(C 19 H 12 N 5) 2(H 2 O) 2 ]·5H 2 O(2),were solvothermally synthesized.The title compounds were characterized by X-ray crystallography and IR.Compound 1 consists of organic ligands and crystallization water molecules.Compound 2 was linked to form 1D chain by hydrogen bonds and further to construct 3D structure by π-π interaction between ligands.TG and FL analysis indicates that compound 2 has good thermal stability and exhibits emission in the solid state at room temperature.
