Back Cover: A Light-Induced Phase Exhibiting Slow Magnetic Relaxation in a Cyanide-Bridged [Fe4Co2] Complex (Angew. Chem. Int. Ed. 26/2012)
Photoswitchable single-molecule magnets are attractive materials that may find applications in future molecular devices. In their Communication on page 6361 ff., H. Oshio and co-workers describe a cyanide-bridged [Fe4Co2] extended square-type complex that displays a thermal and light-induced electron-transfer-coupled spin transition. The light-induced phase transition at low temperature leads to ferromagnetic interactions between the metal ions and the onset of slow magnetic relaxation.
