Tunable magnetism in metal organic frameworks — •Sebastian Schwalbe¹, Kai Trepte², Gotthard Seifert², and Jens Kortus¹ — ¹TU Bergakademie Freiberg, Institute for Theoretical Physics, Germany — ²Technische Universität Dresden, Theoretical Chemistry, Germany

We present a density functional theory based guideline how to combine local magnetism represented by single molecule magnets (SMMs), with the three-dimensional nature of metal organic frameworks (MOFs). Recently, the electronic and magnetic structure of the flexible MOF DUT-8(Ni) was described by Trepte et al. [1]. Based on our previous work we performed a screening of the metal centers in a model system, which is a good approximation for the secondary building unit (SBU) of DUT-8(Ni). The main result of these calculations is, that the electronic structure of this SBU is mainly determined and influenced by the metal centers (3d metals). By varying the metal centers we are able to tune the magnetic properties and obtain stable non-magnetic, ferromagnetic, anti-ferromagnetic or eventually even metallic SBU.
