Treatment of [Ln(BH 4) 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(BH 4) 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.
在四氢呋喃（THF）中，用3和4摩尔当量的KSBT处理[Ln(BH₄)₃(THF)₃]（Ln = Ce，Nd），分别得到[Ln(SBT)₃(THF)]和[K(THF)Ln(SBT)₄]。铀（IV）化合物[U(SBT)₄(THF)₂]由U(BH₄)₄制得，并被钠汞齐可逆还原为相应的阴离子铀（III）配合物。[Ln(SBT)₃(THF)₂]（Ln = Ce，Nd）、[K(15 - 冠 - 5)₂][Nd(SBT)₄]、[U(SBT)₄(THF)]和[K(15 - 冠 - 5)₂][U(SBT)₄(py)]的晶体结构显示了SBT配体的双齿配位模式和硫代酸根特征。
