The aim of this paper is to introduce a synthetic concept suitable for the preparation of a broad variety of compounds. The so-called anhydride route (in this article the term anhydride is used for compounds derived from corresponding acids by formal loss of H2O, H2S and H2Se) has so far led to a range of unusual Group 15/16 ligands in oligomeric and polymeric environments. Commonly, reactions of neutral precursor molecules, for example, [{RP(S)(mu-S)}2] (R=4-anisyl) Lawesson's reagent or [{PhP(Se)(mu-Se)}2] Woollins's reagent and metal salts are performed to result in novel coordination compounds in which ligands and metal atoms form coordination oligomers and polymers. An attempt is made to relate the outcome of the investigations to the type of metal used. By relating the strength of ionic interactions, which correspond to metal-donor distances, to phenomena observed in the solid-state structures, an aspect of supraionic chemistry is described. Chemistry of and beyond novel Group 15/16 anions is further discussed using a novel approach in coordination chemistry where the chemical nature of ligands is unknown prior to the experiment despite the use of a range of similar starting materials.
本文旨在介绍一种适用于制备多种化合物的合成概念。所谓的酸酐路线（在本文中，酸酐一词用于指通过形式上失去H₂O、H₂S和H₂Se而从相应酸衍生的化合物）迄今为止已在低聚和聚合环境中产生了一系列不寻常的第15/16族配体。通常，进行中性前体分子的反应，例如，[{RP(S)(μ-S)}₂]（R = 4-甲氧基苯基）劳森试剂或[{PhP(Se)(μ-Se)}₂]伍林斯试剂与金属盐的反应，以得到新型配位化合物，其中配体和金属原子形成配位低聚物和聚合物。尝试将研究结果与所用金属的类型联系起来。通过将对应于金属-给体距离的离子相互作用强度与在固态结构中观察到的现象联系起来，描述了超离子化学的一个方面。使用配位化学中的一种新方法进一步讨论了新型第15/16族阴离子及其以外的化学，在该方法中，尽管使用了一系列相似的起始材料，但在实验之前配体的化学性质是未知的。
