Abstract

207Pb NMR powder pattern analysis has been applied to several lead-containing incrganic and organic compounds. The chemical shielding tensors obtained are less susceptible to systematic error than earlier studies employing magic-angle spinning sideband analysis. Since the lead atom is very sensitive to its local environment, a correlation between the chemical shift and structure was investigated. An increase in Pb-O interatomic distance tends to shift the isotropic chemical shift (δiso) to lower frequency, whereas conversely an increase in Pb-halogen interatomic distance tends to increase the chemical shift. As a consequence of the electronic structure of Pb2+, almost all 207Pb shielding tensors of Pb2+ species have a negative anisotropy.
