Abstract
In this work, five new lanthanide complexes with varying counterions and coordination by fluorinated alkoxide ligands were synthesized and characterized via single crystal X-ray diffractometry, including [K(THF) 2 ][Ln(pin F ) 2 (THF) 2 ] (Ln = Yb, Lu), 3-Ln-K, [Li(THF)][Eu(pin F ) 2 (THF) 3 ], 4-Eu-Li, and [Li(THF)] 3 [Ln(pin F ) 3 (THF)] (Ln = Ce, Eu), 5-Ln-Li. Differences in planarity of a diamond core in bis-perfluoropinacolate species were found across the series of lanthanides. Changing the counterion resulted in significant structural changes, indicated by differences in the degree of THF solvation and buried volume. Increasing the stoichiometry of the synthesis revealed a pinwheel structure that was more symmetric by reflection than a three-fold rotation, and cyclic voltammetry of 5-Ce-Li showed an oxidation event at +0.45 V and a reduction event at –1.79 V relative to ferrocene.
