Pentanuclear and Octanuclear Manganese Helices

Invited for the cover of this issue is the group of Hiroki Oshio at the University of Tsukuba, Japan. The cover image shows the metaphoric link between the synthesis of two new manganese clusters and the ancient Japanese art of origami. Origami literally means “folded paper” and allows elaborate shapes to be created from the simplest materials, just like the rigid, planar ligands that were employed to “fold” manganese ions into sophisticated helical superstructures. Self‐assembly is perhaps the most beautiful but challenging aspect of cluster chemistry, which can gratify and frustrate coordination chemists in equal measure...
