| Abstract: 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(C19H12N5)2(H2O)2]·5H2O (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. CCDC: 786196, 1; 786195, 2. |
