Inside Cover: A [Mn32] Double-Decker Wheel (Angew. Chem. Int. Ed. 19/2011)
A mixed-valent [Mn32] cluster with a very unusual “double-decker” wheel topology is described by E. K. Brechin, A. J. Tasiopoulos et al. in their Communication on page 4441 ff. It is by far the highest-nuclearity example of its type and one of the largest known manganese clusters, and it displays single-molecule-magnet behavior with the largest effective barrier to magnetization relaxation of any molecular wheel.
