A new set of electronegativity scale for trivalent lanthanides

摘要

A new set of electronegativity (EN) scale for all trivalent lanthanides (Ln) is proposed on the basis of effective ionic potential, from which the electron-attracting power of trivalent Ln can be well differentiated. This new scale can be used to qualitatively explain the valence stability and valence change of some typical trivalent Ln. Furthermore, the good linear relationships of the charge-transfer energy of Ln(3+) and the first dehydroxylation temperature in the agardite to the current EN scale of Ln(3+) show us the further reasonableness of our new EN scale.
