Structural Chemistry of Rare-Earth Elements
This chapter begins with a description of the characteristic properties of the lanthanide elements, including their metallic and ionic radii (lanthanide contraction), crystal structures, oxidation states, electronic states, and magnetic properties. Their oxides and halides, and the coordination geometry of their cations are discussed. The section on organometallic compounds of the lanthanides is mainly concerned with those with cyclic organic ligands such as benzene, cyclopentadienyl, or cyclooctatetraenyl groups. The chapter concludes with a section on the reduction chemistry of the +2 oxidation state.
Keywords: rare-earth metals, decamethyl samarocene, lanthanide complexes, lanthanide contraction, lanthanide(II) reduction chemistry, lanthanides, rare-earth metal complexes, term symbols of lanthanides
