Synthesis of bulky hydride ligands: <i>m</i>-terphenylborohydride complexes with trivalent uranium and neodymium
Here we describe the first coordination complexes containing a bulky <i>m</i>-terphenyltrihydroborate ligand. Treating [UI<sub>3</sub>(thf)<sub>4</sub>] and NdCl<sub>3</sub> with three equiv. of Li(H<sub>3</sub>BAr<sup><i>t</i>Bu4</sup>)(Et<sub>2</sub>O) (where Ar<sup><i>t</i>Bu4</sup> = 2,6-(3,5-<sup><i>t</i></sup>Bu<sub>2</sub>C<sub>6</sub>H<sub>3</sub>)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>) yielded [M(H<sub>3</sub>BAr<sup><i>t</i>Bu4</sup>)<sub>3</sub>(thf)<sub>2</sub>] (M = U and Nd). [U(H<sub>3</sub>BAr<sup><i>t</i>Bu4</sup>)<sub>3</sub>(dme)<sub>2</sub>] is also described, and structural comparisons reveal the influence of the Lewis base on H<sub>3</sub>BAr<sup><i>t</i>Bu4</sup> positioning.
