45_30/2006Cover Picture: A Ferromagnetically Coupled Mn19 Aggregate with a Record S=83/2 Ground Spin State (Angew. Chem. Int. Ed. 30/2006)

King of the spins is provided by the mixed-valent Mn19 aggregate as reported by A. K. Powell et al. in their Communication on page 4926 ff. The use of bridging azido ligands leads to a completely ferromagnetically coupled system with a record ground spin state of 83/2. This remarkable molecule has been investigated and characterized by scientists from three laboratories working together in the European Network of Excellence “MAGMANet”, the logo of which provides the background to the cover picture.

Photoactivateable proteins, nucleic acids, and small-molecule compounds offer numerous possibilities for investigating biological processes, even in cells. In their Review on page 4900 ff, G. Mayer and A. Heckel summarize recent developments in this field.


Nanotubesfor002

In their Communication on page 4922 ff., C. Ye et al. report the preparation of SrAl2O4 nanoscrolls through a roll-up process under hydrothermal conditions. Post-annealing transforms the nanoscrolls into crystalline nanotubes.


Self-assemblyfor003

PrIII ions and chiral ligands can diastereoselectively build two different superstructures, in which the ligands form helical domains and are attached to trigonal Pr3 or pyramidal Pr4 metallic scaffolds. Details of this solvent-induced self-assembly process can be found in the Communication by O. Mamula et al. on page 4940 ff.
