Gatteschi et al. [44] prepared linear chain polymers that were composed of M(hfac)2(NIT)R, where M is Cu(II), Ni(II), or Mn(II) (NIT)R is 2-alkyl-4,4,5,5-tetramethylimidazoline-l-oxyl-3-oxide and hfac is hexafluoroace-tylacetonate. Ferromagnetic ordering was observed for those polymers composed of Mn(hfac)2(NIT)Et (36) and Ni(hfac)2(NIT) Pr, respectively. The critical temperature for each polymer was 8.6 and 5.3 K, respectively.
