[B(O<sub>2</sub>C<sub>2</sub>(CF<sub>3</sub>)<sub>4</sub>)<sub>2</sub>]<sup>−</sup> ([FPB]<sup>−</sup>): Repurposing This Weakly Coordinating Anion for Solid-State Molecular Organometallic (SMOM) Chemistry
The perfluoropinacol borate-based anion [B-(O<sub>2</sub>C<sub>2</sub>(CF<sub>3</sub>)<sub>4</sub>)<sub>2</sub>]<sup>-</sup>, <b>[FPB]</b> <sup>-</sup>, is developed as a weakly coordinating anion for single-crystal to single-crystal organometallic solid/gas reactivity, resulting in the isolation and characterization (including periodic DFT and IGMH analysis) of the σ-alkane complex [Rh-(Cy<sub>2</sub>PCH<sub>2</sub>CH<sub>2</sub>PCy<sub>2</sub>)-(<i>exo</i>-η<sup>2</sup>η<sup>2</sup>-norbornane)]-[FPB]. The synthetically useful solvent-free Na<sup>+</sup> salt, Na-[FPB], and oxonium acid [H-(OEt<sub>2</sub>)<sub>2</sub>]-[FPB] are also reported.
