Abstract

Spectacular developments in recent years, especially the discovery of an anionic complex of divalent lanthanum, in which the electron is trapped in a localized 5d1 SOMO (see structure of the anion of [K([2.2.2]crypt)][LaCp′′3] (Cp′′=1,3-(SiMe3)2C5H3); La red, C gray, Si black), have brought new impetus to the solution chemistry of divalent lanthanides.
