Electronic structure and magnetic properties of a macrocyclic dinickel complex — •Kai Trepte, Claudia Loose, and Jens Kortus — Institut für theoretische Physik
We present first-principle density functional theory (DFT) calculations on an triply bridged dinickel complex[1] including a hexaaza-dithiophenolate ligand. All DFT calculations are done using the all-electron NRLMOL program package. We focus on the electronic structure close to the Fermi level and calculate the magnetic exchange coupling J using the Heisenberg hamiltonian H=-2JS1→S2→ (S1→=S2→=1). We compare our results with known trends within this class of molecules[2].
