摘要
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 Fe-19 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.
