S, Se, Te)配体，x从1（例如，[Na2Fe18S30] 8 ' ' 4）到9（例如，[(89)]1-4）。到目前为止，在离散型多硫族化合物中，Q42~配体是最常见的。高温化合物往往是扩展的，三维的，固体结构，含有Q2~或Q22~配体。较高的qx2 '配体对高温下固态化合物的稳定性太敏感。它们解离成低硫族化合物和硫。一般来说，低温化合物可以被看作是亚稳态的，因此能够通过有趣的、可能是可分离的低维中间体转化为高温固态化合物。这些可能发生在中间温度范围（约150-350℃）。人们对亚稳低维多硫族化合物的兴趣与日俱增，不仅是因为这些材料的催化和电子特性，还因为它们在分子化学和固态化学之间架起了一座桥梁。迄今为止，在系统的(1)(a) Draganjac， M.；劳赫弗斯，t.b.安格。化学。, Int。编辑。英语。1985,24,742-757。(b)穆勒，a；Diemann大肠;jost r;博格，H.安格。化学。, Int。编辑。英语。1981,20,934-955。(3)刘建军，刘建军。(d)西澳大利亚州弗洛默；奥尼尔，南卡罗来纳州；科德斯，a.w.；信,d;J.

S, Se, Te) ligands with x ranging from 1(eg,[Na2Fe18S30] 8" 3 4) to 9 (eg,[(89)] 1-4). By far, among the discrete poly-chalcogenides, the Q42~ ligands are the most frequently occurring. The high-temperature compounds tend tobe extended, threedimensional, solid-state structures containing either Q2~ or Q22~ ligands. The higher Qx2'ligands are too thermally sensitive to be stabilized in solid-state compounds from high temperatures. 5 They dissociate to lower polychalcogenides and sulfur. In general, the low-temperature compounds can be viewed as metastable and thus capable of transforming to their high-temperature solid-state counterparts via interesting and perhaps isolable low-dimensional intermediates. These could occur in the intermediate temperature range (ca. 150-350 C). Increasing interest in metastable lowdimensional polychalcogenides derives not only from the catalytic6 and electronic properties of these materials7 but also because they offer a bridge between molecular and solid-state chemistry. To date, a very limited effort has beeninvested in the systematic (1)(a) Draganjac, M.; Rauchfuss, T. B. Angew. Chem., Int. Ed.
