Abstract
Phenyl rings substituted NH hydrogen atoms of 2,6-bis(benzimidazol-2-yl)pyridine to obtain ligand,2,6bis(1-phenylbenzimidazol-2-yl)pyridine(bpbp).A new cationic complex,[Ir(bpbp) 2 ](PF 6) 3,was synthesized by treatment IrCl 3 ·6H2 O 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, 1 HNMR,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) nm 3,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 CH2 Cl2 solution.
