Anion-π based compounds, materials, and processes have gained significant interest due to the diversity of their aesthetic non-covalent synthons, and thanks to their significance in biological systems, catalytic processes, anion binding and sensing, or the supramolecular organization of hierarchical architectures. While systems based on typical inorganic anions or organic residues have been widely reviewed in recent years, those involving anionic d metal comlexes as the main components have been treated with a rather secondary interest. However, actively exploring the new systems of the latter type we have recognized systematic advances in the field. As a result, in the current review we describe the landscape that has recently emerged. Focusing on the established groups of π-acidic species, i.e. polycarbonitirles, polyazines, polyazine N-oxides, diimide derivatives, fluoroarenes, and nitroarenes, we explore and discuss anion-π crystal engineering together with the structure-property schemes important from the standpoint of charge transfer (CT) and electron transfer (ET), magnetism, luminescence, reactivity and catalysis, and the construction of core-shell crystalline composites.
基于阴离子-π 的化合物、材料和工艺因其美学非共价合成子的多样性而引起了极大的兴趣，并且由于它们在生物系统、催化过程、阴离子结合和传感或分级结构的超分子组织中的重要性而受到关注。虽然近年来已经广泛综述了基于典型无机阴离子或有机残基的系统，但作为主要成分的含阴离子 d 金属配合物的系统受到了相当次要的关注。然而，通过积极探索后一类新型系统，我们认识到该领域的系统进展。因此，在当前的综述中，我们描述了最近出现的领域。本综述重点关注已建立的π-酸性物质组，即聚碳酸酯、聚嗪、聚嗪 N-氧化物、二酰亚胺衍生物、氟代芳烃和硝代芳烃，我们探索和讨论了阴离子-π 晶体工程以及从电荷转移 (CT) 和电子转移 (ET)、磁性、发光、反应性和催化以及核壳结晶复合材料的构建角度来看重要的结构-性质方案。
