Exploring the synthesis and structure of copper(II)-oxo clusters Tom Barnes, Sebastian Pike University of Warwick, UK Copper(II)-oxo clusters are a relatively unexplored class of copper coordination compounds. Some Cu(II)-oxo clusters have gained research attention through their applications as models for enzyme active sites, [1] catalysts, [2] single molecule magnets, [3] and as anion encapsulating agents. [4] Cu(II) is an intriguing target for making metal- oxo clusters of different shapes and sizes due to its flexible coordination geometries and Jahn-Teller effects. [5] The synthesis of Cu(II)-oxo clusters is currently poorly understood, with synthetic routes relying on slow crystallisation processes. [6] We have explored using the controlled hydrolysis of a smaller, pre-hydrolysis , cluster (i.e. no oxide/hydroxide ligands) to optimise, and control, their synthesis. We have also used techniques such as X-ray diffraction, electrochemistry, UV-vis and X-ray photoelectron spectroscopies to explore the physical and electronic structures of these clusters. An understanding of these properties will guide potential applications, such as for use as photocatalysts or as precursors for functional materials. References 1. S. Grundner, M. A. C. Markovits, G.
