"Ln(TePh)(3)" (Ln = Er, Tm, Lu), prepared in situ by the reduction of PhTeTePh with elemental Ln in the presence of Hg catalyst, reacts with elemental Te to give heterometallic clusters with the formula (py)(7)Ln(3)HgTe(4)(TePh)(3). Structural characterization of all three isostructural derivatives reveals a cubane arrangement of metal ions, with a distorted tetrahedral Hg(II) ion coordinated to three mu(3) coordinate Te(2-) and a terminal TePh ligand. There are two chemically inequivalent types of octahedral Ln(III) ions, one bound to three Te(2-) and three pyridine donors, and two that coordinate two pyridine, three Te(2-), and a terminal TePh ligand. The Lu compound decomposes at elevated temperatures to give LuTe.
"Ln(TePh)(3)"（Ln = Er，Tm，Lu），通过元素 Ln 与 PhTeTePh 在 Hg 催化剂存在下还原原位制备，与元素 Te 反应得到通式为(py)(7)Ln(3)HgTe(4)(TePh)(3)的杂金属簇合物。对所有三种同构衍生物的结构表征揭示了金属离子的立方烷排列，其中一个畸变的四面体 Hg(II)离子与三个μ(3)配位的 Te(2-)和一个末端 TePh 配体配位。有两种化学不等价的八面体 Ln(III)离子，一种与三个 Te(2-)和三个吡啶供体配位，两种与两个吡啶、三个 Te(2-)和一个末端 TePh 配体配位。Lu 化合物在高温下分解生成 LuTe。
