    Getting down to business: Reduction of the LaIII tricyclopentadienide complex [LaCpâ€Čâ€Č3] (Cpâ€Čâ€Č=η5-1,3-(SiMe3)2C5H3) by K and [18]crown-6 or [2,2,2]cryptand produced thermally stable mononuclear crystalline lanthanate(II) salts. The La +2 oxidation state in these complexes was confirmed both in solution (EPR) and the solid state (EPR, SQUID, X-ray diffraction) and was supported by a computational study
