Abstract
Asymmetrically-bound pyrrollide-based bis-PNP pincer complexes of zirconium and hafnium
have been formed. The [κ2-PNPPh][κ3-PNPPh]MCl2 species are in direct contrast to previous
zirconium PNP pincer complexes. The pincer ligands are fluxional in their binding and the
energy barrier for exchange has been approximated using VT-NMR spectroscopy and the
result validated by DFT calculations.
