Back Cover: Two Linear Undecanickel Mixed-Valence Complexes: Increasing the Size and the Scope of the Electronic Properties of Nickel Metal Strings (Angew. Chem. Int. Ed. 9/2011)
The longest metal string reported to date for a single molecule comprises 11 nickel atoms. The mixed-valent NiI and NiII centers are arranged linearly and wrapped by four helical ligands. Flanking the molecular structure are images of the real molecular model that is on display in the Chemistry Building at the National Taiwan University, where the compound was designed and prepared. In their Communication on page 2045 ff. M. Bénard, S.-M. Peng, and co-workers also report the electronic and magnetic properties of this Ni11 complex.
