Towards nanostructured arrays of single molecule magnets: new Fe19 oxyhydroxide clusters displaying high ground state spins and hysteresis

Author affiliations

Abstract

Ligands of general formula N(CHRCH2OH)(CH2CO2H)2 have been used to capture portions of the Fe(OH)2+ lattice to give particles containing up to nineteen magnetically coupled iron(III) centres. If R = Me or Et, lattices containing only Fe19 clusters result and single crystal X-ray diffraction shows that these are arranged in tilted stacks. These clusters act as single molecule magnets, pointing the way forward to engineering ordered arrays of magnetic particles. The packing of such materials is independent of the counter anion, NO3 or Cl, used.
