[(THF)3Sm(SePh)2Zn(SePh)2]n decomposes to give a variety of products, including (THF)8Sm4Se(SePh)8Zn8Se(SePh)16, an ionic cluster that can also be prepared in more than 60% yield by stoichiometric addition of Se to a mixture of Sm(SePh)3 and Zn(SePh)2. The isostructural Nd compound (THF)8Nd4Se(SePh)8Zn8Se(SePh)16 was also prepared by the stoichiometric route to establish the viability of this cluster type with redox-inactive Ln. In addition, the salt Yb(THF)6Fe4Se4(SePh)4 was isolated and structurally characterized. These ionic cluster materials illustrate the difficulties associated with doping Ln ions into covalent metal chalcogenido matrixes.
[(THF)₃Sm(SePh)₂Zn(SePh)₂]ₙ分解会产生多种产物,包括(THF)₈Sm₄Se(SePh)₈Zn₈Se(SePh)₁₆,这是一种离子簇,通过向Sm(SePh)₃和Zn(SePh)₂的混合物中化学计量地添加Se,也能以超过60%的产率制备得到。通过化学计量路线还制备了同构的钕化合物(THF)₈Nd₄Se(SePh)₈Zn₈Se(SePh)₁₆,以确定这种具有氧化还原惰性镧系元素的簇类型的可行性。此外,分离并对盐Yb(THF)₆Fe₄Se₄(SePh)₄进行了结构表征。这些离子簇材料说明了将镧系离子掺杂到共价金属硫属化物基质中所面临的困难。
