Back Cover: Double Switching of a Magnetic Coordination Framework through Intraskeletal Molecular Rearrangement (Angew. Chem. Int. Ed. 17/2011)
The reversible removal of guest molecules in Mn2Nb magnetic coordination framework materials, as described by D. Pinkowicz, B. Sieklucka et al. in their Communication on page 3973 ff., causes a spectacular two-step molecular rearrangement of their skeleton involving the topotactic formation of an additional molecular bridge and the translocation of the incorporated organic ligand. These structural changes impact the magnetic ordering temperature and allow for its switching between 43, 68, and 100 K.
