双核[(NiL)Gd(hfac)(2)(EtOH)](H(3)L = 1,1,1-tris(N-亚水杨基氨甲基)乙烷,Hhfac =六氟乙酰丙酮)、三核[(NiL)(2)Gd(NO(3))]和四核[(NiL)Gd(CH(3)CO(2)(2)(MeOH)](2)配合物,通过用[Gd(hfac)(3)(H(2)O)(2)]处理[Ni(HL)]制备,Gd(NO(3))(3)·6H(2)O和Gd(CH(3)CO(2))(3)·4H(2)O。所有的配合物表明,铁磁相互作用之间发生的Ni(II)和Gd(III)离子。
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.
