Electron Paramagnetic Resonance Spectroscopy of Vanadium (IV) Complexes and Related Species

摘要

The report details the successful application of e.p.r. spectroscopy to the study of vanadium(IV) oxohalide complexes. In particular, it has proven an invaluable structural tool for relating the structure of a complex in an amorphous or polycrystalline sample to that of the same complex in solution. Moreover, solution studies by e.p.r. have revealed previously unsuspected dissociation and displacement phenomena for complexes of the type (VOX2Ln) (X=C1 or Br, L=mono- or bi-dentate ligand), which means that many literature reports need to be reexamined. A comprehensive literature survey is included. (Author)
