摘要：
The 1:1:2 mixture of Ln(hfac)(3), Zn(hfac)(2), and NIT-Pyrim (hfac = hexafluoroacetylacetonate, NIT-Pyrim = 2-pyrimidine-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) afforded a series of 2p-3d-4f magnetic chains [Ln(hfac)(3)Zn(hfac)(2)(NIT-Pyrim)(2)] [Ln(III) = Gd (1), Ho (2), Yb (3)], in which Zn(hfac)(2) and Ln(hfac)(3) units are bridged by pyrimidine substituted nitronyl nitroxides through their NO moieties and pyrimidine nitrogen atoms. These complexes represent the first examples of 2p-3d-4f complexes with Zn-II ions. Magnetic studies show that there exist ferromagnetic exchange couplings between the coordinated NO groups of radical ligands and the Gd-III ions.
