Abstract: Atomically precise group 11 nanoclusters (NCs) are currently of intense interest, both for their fundamental properties and for their potential use in a wide variety of applications, including catalysis. As a result, the last 5 years have seen significant progress in the synthesis of well-defined, mono-disperse group 11 nanoclusters.  Yet, while many examples of thiol-passivated silver and gold NCs are now known, comparable copper NCs have remained elusive due, in part, to their higher air-sensitivity.  In this presentation I will describe the syntheses of several atomically precise Cu NCs, including the organometallic NC, [Cu20(CCPh)12(OAc)6], which can also be described as N* = 2 superatom.  Additionally, I will discuss their characterization by a variety of techniques, including XANES and EXAFS, as well as our initial efforts to synthesize NCs of Fe, Co, and Ni.
