In this Dalton Transactions Hot Article, Richard Winpenny and colleagues report the characterisation of isolated finite chromium based horseshoe shaped chains.  The team used INS, magnetic and EPR techniques to determine the inter-chromium exchange coupling and single ion zero field splitting (ZFS) within the chain segments.

Manipulating quantum spin levels via ligands, which play no role in super-exchange, is of general interest to the practise of spin Hamilton modelling.
