Overview
We are organometallic chemists interested in the stabilisation of highly unsaturated compounds involving earth abundant main group and transition elements. These compounds often display unusual structures and reactivities associated with their coordinative unsaturation, which we investigate in applications such as small molecule activation and valorisation, novel reaction catalysis, energy storage and magnetism.
Our research projects involve inorganic and organic synthetic methods, small molecule reactions, catalysis, in situ reaction monitoring, mechanistic investigations and magnetism, using a range of physical characterisation methods including multinuclear NMR, IR, EPR and Mössbauer spectroscopies, X-ray diffraction and magnetochemistry, work collaboratively with other research groups.

Research
Our research group is interested in the synthesis of low-coordinate organometallic complexes featuring main group or transition elements, these highly reactive compounds being stabilised by sterically demanding ligand systems. We are particularly interested in the exploitation of the unusual structures of these compounds and the investigation of fundamental patterns of reactivity under stoichiometric and catalytic regimes. Some representative projects within our research group involve:
- Scission and homologation reactions of small molecules, valorisation
- Earth abundant transition metal complexes for catalytic applications, e.g. heterofunctionalisation, cyclotrimerisation
- Organometallic complexes for energy storage and catalysis
- Multidentate ligand design for heterobimetallic complexes
- Low-coordinate complexes for single molecule magnetism
