Abstract

Treatment of [Ln(BH₄)₃(THF)₃] (Ln = Ce, Nd) with 3 and 4 mol equiv of KSBT in tetrahydrofuran (THF) led to the formation of [Ln(SBT)₃(THF)] and [K(THF)Ln(SBT)₄], respectively. The uranium(IV) compound [U(SBT)₄(THF)₂] was obtained from U(BH₄)₄ and was reversibly reduced by sodium amalgam into the corresponding anionic uranium(III) complex. The crystal structures of [Ln(SBT)₃(THF)₂] (Ln = Ce, Nd), [K(15-crown-5)₂][Nd(SBT)₄], [U(SBT)₄(THF)], and [K(15-crown-5)₂][U(SBT)₄(py)] show the bidentate coordination mode and the thionate character of the SBT ligand.

  Abstract: X-ray diffraction and DFT analysis show that the pentagonal bipyramidal uranium(III) complex [U(Cp*)(SBT)₃]⁻ can be clearly differentiated from its lanthanide analogues by the distinctly more covalent character of the axial U−N bond.
