Summary on Grant Application Form
The study of low oxidation state and multiply bonded main group metal systems constitutes one of the most fundamentally interesting and controversial areas of main group chemistry currently under investigation. Despite the synthesis of numerous text-book molecules, the bonding in compounds containing homo- or heteronuclear multiple bonds involving the heavier main group elements has been debated exhaustively in the literature over the last five years. It has become clear not only that experimental spectroscopic evidence is not a reliable probe for the level of multiple bonding in heteronuclear charge-separated systems, but also that current theoretical methods are not sufficiently sophisticated to accurately describe homo- and heteronuclear multiple bonding.We propose to overcome these problems using an integrated approach (synthesis, experimental charge density studies, high level calculations) to unambiguously define the nature of the bonding in both novel and existing low-coordinate main group systems. Most importantly, this approach will incorporate, for the first time, charge density studies as an unequivocal probe of electronic structure in such systems. Once we have established our integrated approach, it will undoubtedly be recognised as a technique of major fundamental significance by the international community and will, unquestionably, be applied by other groups to the solution of similar problems.
