Reductive cleavage of C(6)F(5)SeSeC(6)F(5) with elemental M (M = Zn, Cd, and Hg) in pyridine results in the formation of (py)(2)Zn(SeC(6)F(5))(2), (py)(2)Cd(SeC(6)F(5))(2), and Hg(SeC(6)F(5))(2). Structural characterization of the Zn and Cd compounds reveals tetrahedral coordination environments, while the Hg compound shows a complicated series of linear structures with two short, nearly linear Hg-Se bonds, up to two longer and perpendicular Hg...Se interactions, and no coordinated pyridine ligands. All three compounds exhibit well-defined intermolecular pi-pi-stacking interactions in the solid state. They are volatile and decompose at elevated temperatures to give MSe and either (SeC(6)F(5))(2) or Se(C(6)F(5))(2).
用元素 M（M = Zn、Cd 和 Hg）将 C(6)F(5)SeSeC(6)F(5) 还原裂解在吡啶中，生成(py)(2)Zn(SeC(6)F(5))(2)、(py)(2)Cd(SeC(6)F(5))(2)和 Hg(SeC(6)F(5))(2)。Zn 和 Cd 化合物的结构表征表明它们具有四面体配位环境，而 Hg 化合物则表现出一系列复杂的线性结构，其中包含两个短的、近乎线性的 Hg-Se 键，两个更长且垂直的 Hg...Se 相互作用，以及没有配位的吡啶配体。所有三种化合物在固态中都表现出明确的分子间π-π 堆积相互作用。它们具有挥发性，在高温下分解生成 MSe 和(SeC(6)F(5))(2)或 Se(C(6)F(5))(2)。
