Two Ln-Ni heterometallic complexes connected with nitronyl nitroxides have been synthesized and characterized, showing rare radical bridged structures. Magnetic studies indicate that the magnetic exchanges arising from the uncoordinated NO groups dominate the system, with the Tb compound displaying a slow relaxation of magnetization.
Two Ln-Ni heterometallic complexes connected with nitronyl nitroxides [Ln(hfac)3Ni(hfac)2NIT-4py(H2O)2] (Ln = Gd (1), Tb (2); hfac = hexafluoroacetylacetonate; NIT-4py = 2-(4-pyridyl)-4,4,5,5-tetramethylimidazoline-1oxyl-3-oxide) have been synthesized as well as characterized. For two complexes, the NIT-4py radical is ligated to the Ln(III) ion and Ni(II) ion via its NO moiety and pyridine-N atom, respectively, resulting in rare radical bridged Ln-Ni heterobinuclear structure. Magnetic studies reveal that the magnetic exchanges arising from the uncoordinated NO groups dominate the system. Interestingly, the Tb compound displays a slow relaxation of magnetization.
