Dr. Nathan J. Patmore
Royal Society University Research Fellow
Dr. Patmore obtained a BSc in Chemistry from the University of Bath in 1999, which was followed by a PhD from the same institution in 2002 under the supervision of Dr. Andrew Weller. Following his PhD, he did post-doctoral research with Prof. Malcolm Chisholm at The Ohio State University, USA. In 2005, he was awarded a Ramsay Memorial Research Fellowship which was hosted by the University of Sheffield, and in 2006 he became a Royal Society University Research Fellow.

My research interests are based upon the chemistry of metal-metal multiply bonded compounds, typically incorporating metals from groups 6, 7 or 8, containing a dimetal core supported by four bidentate three-atom ligands, such as a carboxylate.
The metal-metal bond in these systems can have a formal bond order of up to four, which make these species particularly suited for fundamental studies of chemical bonding. For example, we observed an unusual reduction in metal-metal bond length despite an increase in the formal bond order for a series of diruthenium complexes. With the aid of theoretical calculations, we demonstrated this unusual phenomenon was related to distortion of the ligand environment due to changes in the electronic structure.
We have a number of projects that aim to utilize the redox active nature and interesting photophysical properties of the dimetal core. These includes the incorporation of the dimetal core into materials with interesting optoelectronic and magnetic properties, and their use in the study of mixed-valency and electron transfer processes in multinuclear systems generated using bridging ligands or hydrogen bonding interactions. Inspired by the diiron active site in a variety of non-haem enzymes, we are also exploring the application of diiron and diruthenium compounds as catalysts in aerobic oxidation reactions.
Our research employs Schlenk-line and glovebox techniques for the synthesis of our compounds which are often air-sensitive. The department has excellent facilities for characterization and evaluation of these compounds, which includes MALDI-TOF, mass spectrometry, NMR spectroscopy, electrochemistry, UV/vis and IR spectroscopy and X-ray diffraction. During their projects researchers get training and ‘hands-on’ experience in all these techniques.
