Binuclear
complexes with general formula [Ln2(hfac)6(H2O)2(dppnTEMPO)] (LnIII = Gd, Tb,
and Dy) have been obtained using the paramagnetic ligand 1-piperidinyl-4-[(diphenylphosphinyl)amino]-2,2,6,6-tetramethyl
(dppnTEMPO) as a bridge. One of the lanthanide ions is ferromagnetically
coupled with the TEMPO moiety. Two of the complexes (Dy and Tb) show
slow relaxation of the magnetization, and the non-magneto-equivalence
of the two LnIII ions was clearly observed. The ab initio CASSCF calculations were employed to confirm this
behavior, as well as to rationalize the Ln–Rad interaction.
The simulations of the magnetic properties were allowed by the insights
given by the calculations. The inequivalence of the TbIII ions was also proved by emission spectroscopy.
