| Abstract: | Dinuclear (NiL)Gd(hfac)(2)(EtOH)](H(3)L = 1,1,1-tris(N-salicylideneaminomethyl)ethane, Hhfac = hexafluoroacetylacetone), trinuclear (NiL)(2)Gd(NO(3))], and tetranuclear (NiL)Gd(CH(3)CO(2))(2)(MeOH)](2) complexes, were prepared by treating Ni(HL)] with Gd(hfac)(3)(H(2)O)(2)], Gd(NO(3))(3).6H(2)O, and Gd(CH(3)CO(2))(3).4H(2)O, respectively, in the presence of Et(3)N. All the complexes show that ferromagnetic interactions occur between the Ni(II) and Gd(III) ions. |
