'Inverse' Coordination: A New Design Concept in Supramolecular Inorganic Chemistry
Lead Research Organisation:
University of Strathclyde
Department Name: Pure and Applied Chemistry
Abstract
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.

Description | This project was exceptionally productive leading to the publication of 18 high impact papers in international journals. Key advances were made in synergistic synthesis where two metal reagents can perform chemical reactions outside the scope of the single metal reagents from which they are composed. The impact of these findings can be evidenced by the fact that breakthroughs on sodium-zinc and potassium-zinc synergistic systems were published in the leading world class journal "Science". Specifically it was shown that cyclic ethers could be controllably metallated by these bimetallic compositions and sedated from ring opening which occurs invariably when these cyclic ethers are deprotonated by conventional single metal based organometallic reagents. These deprotonated ethers can then be employed in synthetic campaigns. Aside from fundamental interest, this work stimulated interest from the pharmaceutical industry with AstraZeneca sponsoring a future PhD studentship in the bimetallic area. |
Exploitation Route | The results obtained could be useful to synthetic chemists in both organic and inorganic chemistry. |
