| Abstract: Phenyl rings substituted NH hydrogen atoms of 2, 6-bis(benzimidazol-2-yl)pyridine to obtain ligand, 2,6-bis(1-phenylbenzimidazol-2-yl)pyridine (bpbp). A new cationic complex, [Ir(bpbp)2](PF6/sub>)3, was synthesized by treatment IrCl3·6H2O with 2 equiv of 2, 6-bis(1-phenylbenzimidazol-2-yl)pyridine in ethylene glycol at 180 ℃. Its structure was characterized by element analysis, IR, 1HNMR, X-ray single crystal structure analyses. For complex: crystal system monoclinic, space group P2/n, a=1.435 1(5) nm, b=1.094 1(5) nm, c=2.206 9(5) nm, β=99.832(5)°, V=3.414(2) nm3, Z=2. It is an ionic complex. The Ir(Ⅲ) ion octahedral geometry is coordinated by six nitrogen atoms from two ligand. The complex emits green yellow luminescence in CH2Cl2 solution. CCDC: 913646. | |
