Synthetic methods are described that have resulted in the preparation of several mixed-metal Mn-Ce clusters. The methods involve the reaction of MnII salts or preformed Mn clusters with CeIV reagents. The products may be divided into three general classes on the basis of the Mn and Ce oxidation states, MnIV-CeIV, MnIII-CeIV, and MnIII-CeIII/IV. All MnIV-CeIV compounds were prepared by addition of CeIV to MnII salts, whereas all MnIII-CeIV and MnIII-CeIII/IV clusters were prepared by addition of CeIV to MnIII-containing clusters. All the mixed Mn-Ce clusters have aesthetically pleasing structures and some of them also have interesting magnetic properties. © 2006 Elsevier Ltd. All rights reserved.
