Inside Cover: [ReF6]2−: A Robust Module for the Design of Molecule-Based Magnetic Materials (Angew. Chem. Int. Ed. 5/2014)
A robust building block for magnetic systems is found as a result of a new high-yield synthesis of the [ReF6]2– ion. K. S. Pedersen, R. Clérac, J. Bendix, and co-workers report in their Communication on page 1351 ff. that on incorporating the [ReF6]2– in a NiII–ReIV 1D coordination polymer, the fluoride mediates significant magnetic couplings. The ferromagnetic Ni-F-Re interaction found (+11 cm–1) dwarfs the values obtained in related cyanide-bridged systems.
