Relationship between Solid-State ³¹P NMR Parameters and X-ray Structural Data in Some Zinc Phosphonates

Abstract

31P solid-state NMR spectroscopy is a powerful tool to get structural information about the environment of the phosphorus atoms in zinc phosphonates. In a series of various known structures taken as reference, the connectivity of the RPO3 groups (i.e., the number of zinc atoms bonded to each of the three oxygen atoms of the phosphonate units) can be differentiated on the basis of the value of the chemical shift asymmetry and anisotropy.
