Metal organic framework (MOF) materials are porous solids formed from a network of metal centres mainly coordinated to organic linkers. Examples of magnetic MOFs with strong magnetic interactions as a result of 3D superexchange are rare. We have prepared a new MOF material Fe2F5(Htaz) that realises a 3D inorganic network containing Fe(II) and Fe(III) cations. Magnetic susceptibility indicate the dominance of strong antiferromagnetic correlations within Fe2F5(Htaz) and the system appears to undergo an ordering transition at ~ 100 K to a ferrimagnetic state. We request one day on GEM to investigate the evolution of spin order in this new magnetic MOF material as a function of temperature.
