Abstract | The full-potential linearized augmented plane wave (FPLAPW) method with the generalized gradient approximations (GGA) is applied to study the compound [Cu(NTTmPy)(2)(N-3)(2)](n) (NITmPy = 2 - (3' - Pyridyl) - 4,4,5,5 - tetramethylimidazolin - 1 - oxyl - 3 - oxide). The total density of states (DOS) and the partial density of states (pDOS) are calculated to explain the electronic and the magnetic properties of [Cu(NTTmPy)(2)(N-3)(2)](n). It is found that [Cu(NTTmPy)(2)(N-3)(2)](n) is stable in the ferromagnetic state and the magnetic moment of the molecule mainly comes from the Cu atoms (0.518 mu(B)) with partial contribution from N, O atoms of nitronyl nitroxide radicals. There exist orbital hybridization between 3d orbital of Cu and p orbitals of N(1) (from pyridyl rings of the NITmPy ligands) and N(4) (from azido group) and the weak direct exchange interactions between Cu and 0 atoms of nitronyl nitroxides. In addition, the bridging carbon atom (C(6)) carries a significant negative spin density (-0.019mu(B)). The sign alternation of the magnetic moment along the pyridyl ring is obtained, which agrees with experiments. |
