The cover picture shows the structure of a decanuclear cluster [Cu10Cl10(L)4], where L is 3,7-di(3-pyridyl)-1,5-dioxa-3,7-diazacyclooctane, generated by diffusing the CH2Cl2 solution of L into the MeCN solution of CuCl. The two stairlike [Cu5Cl5] fragments share two μ6-Cl and two μ-Cl atoms to form a unique [Cu10Cl10] cluster framework. Details are discussed in the article by Z.-G. Ren, J.-P. Lang et al. on p. 824 ff. For more on the story behind the cover research, see the Cover Profile.
