Single-molecule magnets (SMMs) continue to attract a lot of attention for their potential application to new technologies such as molecule-based information storage, molecular spintronics, molecular refrigeration, and quantum information processing. The ability of SMMs to function as nanoscale magnetic materials at very low temperatures has stimulated interest by inorganic-material chemists in the component properties on which this phenomenon is based: high spin (S) ground states, and easy-axis magnetoanisotropy. Our work with SMMs has been primarily concentrated in manganese cluster chemistry involving at least some Jahn-Teller distorted MnIII ions, the primary source of SMMs to date. The focus of the presentation will be on the synthesis of a novel mixed-valence Mn9  SMM with a large, half-integer spin of S = 21/2, together with extensive data obtained from electrochemical, dc and ac magnetochemical, inelastic neutron scattering, and computational studies. Initial reactivity of several novel alkoxide-based ligands with transition metals will be investigated.
