The synthesis and structural characterization of the first molecular complexes of lanthanide iodides supported by the weak-base, diethyl ether, are reported. Single-crystal diffraction studies reveal a conserved [LnI(mer-EtO)] structure (Ln = Ce, Pr, Nd, Sm, Gd, Tb, and Tm). These precursors are prepared from lanthanide metal and iodine in diethyl ether for all lanthanides La to Tm (excluding Pm and Eu) and provide the THF adducts in good to excellent (60-91%) yield in a two-step process.
报道了由弱碱二乙醚支持的镧系元素碘化物的首个分子配合物的合成及结构表征。单晶衍射研究揭示了一种保守的[LnI(mer-EtO)]结构（Ln = Ce、Pr、Nd、Sm、Gd、Tb和Tm）。这些前体由镧系金属和碘在二乙醚中制备，适用于从La到Tm的所有镧系元素（不包括Pm和Eu），并通过两步法以良好至优异（60 - 91%）的产率提供四氢呋喃加合物。
