Abstract
Two new cationic Pd(II) complexes [PdCl{η2-(P,N)PPh2py}{η1-(N)DiphIm}](PF6) (1) and [PdCl{η2-(P,N)PPh2Etpy}{η1-(N)DiphIm}](PF6) (2), where PPh2py is 2-(diphenylphosphino)pyridine and PPh2Etpy is 2-{2-(diphenylphosphino)ethyl}pyridine), have been synthesized by reacting 4,5-diphenylimidazole (4,5-DiphIm) with the respective complexes [PdCl2{η2-(P,N)PPh2py}] and [PdCl2{η2-(P,N)PPh2Etpy}] in 1:1 molar ratio by stirring in dichloromethane in presence of NH4PF6 under N2 at room temperature. The complexes were characterized by elemental analysis, ESI(+)MS, UV-vis, FTIR, conductivity measurements, thermal analysis and 1H and 31P{1H} NMR studies.
