Structural comparison of [Ce(O<sup> <i>t</i> </sup>Bu)Cl(THF)<sub>5</sub>](BPh<sub>4</sub>) to smaller rare earth analogues
The introduction of the cerium(III) analogue (1-Ce, Ln = Ce) of (tert-butoxido)chloridopentakis(tetrahydrofuran)lanthanide(III) tetraphenylborate tetrahydrofuran disolvate, [Ln{OC(CH<sub>3</sub>)<sub>3</sub>}Cl(C<sub>4</sub>H<sub>8</sub>O)<sub>5</sub>][B(C<sub>6</sub>H<sub>5</sub>)<sub>4</sub>]·2C<sub>4</sub>H<sub>8</sub>O or [Ln(O<sup>t</sup>Bu)Cl(THF)<sub>5</sub>](BPh<sub>4</sub>)·2THF (1-Ln) has been achieved with a structural comparison between the existing solid-state structures of other rare earth analogues and the title compound at 100 and 180 K. The cation in 1-Ce is targeted as the cerium(III) ion possesses the criteria to exhibit slow magnetic relaxation in axial point-charge crystal fields, akin to the dysprosium(III) ion in 1-Dy. AC magnetic susceptibility experiments reveal no such behaviour for 1-Ce, putting the viability of cerium-based SMMs into question.
