3d and mixed 3d/4f metal clusters containing bridging oxide ions continue to be an area of great interest to many research groups, including ours, due to their often fascinating structures and interesting physical properties, particularly those of relevance to the field of molecular magnetism. Manganese is one of the 3d metals of choice for such studies, being stable in multiple oxidation states and having shown a great propensity to yield a variety of cluster types, as well as displaying significant magnetoanisotropy arising from the Jahn-Teller distortion of octahedral MnIII. As a result, Mn/O cluster chemistry often leads to compounds with interesting structural, magnetic, and other physical properties.  The inclusion of CeIV in Mn chemistry can lead to it acting as an oxidizing agent, a source of a heterometal to give mixed-metal products, or both, and when reduced to CeIII can also provide additional anisotropy to mixed-metal products. The syntheses, structural characterization, and physical properties of several new Mn and Mn/Ce clusters will be presented.
