[Tm-III(hfac)(3)(NITPhOPh)](infinity): A new member of a lanthanide-based single chain magnets family

The polymeric coordination compound of formula [Tm(hfaC)(3)(NITPhOPh)](infinity) (where NITPhOPh is a nitronyl-nitroxide radical) has been synthesized and found to belong to the only reported family of isostructural Single Chain Magnets. Both static and dynamic magnetic measurements have been performed, and a dependence of the out-of-phase signal on the frequency is observed below 3 K. Scaling procedures indicate Ising magnetic anisotropy. Comparison of the extracted parameters with those of the previously reported isostructural compounds confirms a trend along the lanthanide series.
