afforded new kinds of PCP and NCN pincer complexes. These pincer complexes containing m-terphenyl scaffolds have been characterized by NMR spectroscopy and single crystal X-ray crystallography. Structure analyses of these pincer complexes reveal a C

symmetric environment. In addition, this system shows the greatest “twist” angle to date for pincer complexes. There has been no evidence of the interconversion of possible atropisomers even at elevated temperature, which indicates the high rigidity of these pincer complexes. Further more, the introduction of chiral imine groups was utilized for resolution of chiral pincer complexes having high degree of non-fluxionality.
