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

虽然在过去的几十年里，阴离子配位的有机宿主已经得到了广泛的研究，但对无机宿主（其框架主要基于非碳原子）的研究却少得多。事实上，这种类型的无机系统在阴离子配位和超分子化学中的潜在普遍用途尚未实现，尽管无机宿主通常比有机宿主（特别是那些含有刘易斯酸性金属原子的宿主）对阴离子具有更大的亲和力。在建立新的合作关系时，该提案寻求利用英国两位主要群体化学研究人员的专业知识，开发和利用盐晶格逆配位的新合成概念，其中一系列优雅的金属基受体将被用作阴离子宿主。一个重要的研究领域是利用逆配位的概念合理设计超分子主基团组合。除了为不寻常的无机和有机金属阴离子的稳定提供手段外，金属基逆配体对简单盐阴离子的固定提供了一种快速离子导体的新方法。

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.
