Abstract

51V static and magic-angle spinning (MAS) NMR spectra of crystalline monovalent metal metavanadates LiVO3, α- and βNaVO3, KVO3, CsVO3, β-AgVO3, and NH4VO3 and divalent metal metavanadates M(VO3)2 (M = Mg, Ca, Sr, Ba, Zn, Pb) have been measured in order to establish the relationships between the various NMR parameters, such as isotropic chemical shift, δiso, chemical shift anisotropy, |Delta;δ|, the asymmetry parameter, η, and the crystallographic parameters. When the structural units are the same, in this case VO4 tetrahedra or VO5 trigonal bipyramids, the δiso decrease almost linearly with decreasing average V-O bond length, independent of the polymerization degree and linkage mode of the VOn polyhedra. |Delta;δ|, increases with the polymerization degree and the degree of the structural distortion of the VOn polyhedron. It is found possible to predict the structural unit and the polymerization degree on the basis of the relation between |Delta;δ| and η.
