'Inverse' Coordination: A New Design Concept in Supramolecular Inorganic Chemistry

在过去的几十年里，人们已经广泛地研究了用于配位阴离子的有机主体，但对无机主体(其框架主要基于非碳原子)的研究要少得多。事实上，这种类型的无机体系在阴离子配位和超分子化学中的潜在普遍用途尚未被认识到，尽管事实上无机主体对阴离子的亲和力往往比有机相关物(特别是那些含有Lewis酸性金属原子的主体)要大得多。在建立一项新的合作时，这项建议寻求利用英国两位主族化学领域的领先研究人员在开发和利用盐晶格反配位的新合成概念方面的专业知识，其中一系列优雅的金属受体将被用作阴离子宿主。一个主要感兴趣的领域是利用逆配位的概念合理地设计超分子主基团组装。除了提供稳定不寻常的无机和有机金属阴离子的手段外，金属基反相配体对简单盐中阴离子的固定化为快速离子导体提供了一种新的方法。

While organic hosts for the coordination of anions have been extensively studied in the past few decades, studies of inorganic counterparts (whose frameworks are based predominantly on non-carbon atoms) have been much rarer. Indeed, the potentially general usefulness of inorganic systems of this type in anion coordination and supramolecular chemistry has not been realised, despite the fact that inorganic hosts frequently offer far greater affinity for anions than organic relatives (particularly those containing Lewis acidic metal atoms). In establishing a new collaboration, this proposal seeks to harness the expertise of two of the UK's leading researchers in main group chemistry in the development and exploitation of the new synthetic concept of inverse coordination of salt lattices, in which a range of elegant metal-based acceptors will be used as anion hosts. A major area of interest is the rational design of supramolecular main group assemblies using the concept of inverse coordination. In addition to providing the means for the stabilisation of unusual inorganic and organometallic anions, the immobilisation of the anions of simple salts by metal-based inverse ligands provides a novel approach to fast-ion conductors.
