两个异三核配合物[Mn-II（（NiL）-L-II）（2）]中心点2CH（3）OH（其中H_3L = 1，1，1-三（N-亚水杨基氨甲基）乙烷）和[Fe-III（NiL-II）（2）]NO（3）中心点C_2H_5OH，由三个共面八面体组成;尽管这些配合物具有密切相关的结构，并且具有相同的1-5/2-1自旋系统，但它们在相邻金属离子之间显示出完全不同的磁相互作用：铁磁性（Ni-II-Mn-II）和反铁磁性（Ni-II-Fe-III）。
Two heterotrinuclear complexes, [Mn-II((NiL)-L-II)(2)]center dot 2CH(3)OH (where H3L=1,1,1-tris(N-salicylideneaminomethyl) ethane) and [Fe-III(Ni L-II)(2)]NO(3)center dot C2H5OH, consisting of three face-sharing octahedra have been prepared; although these complexes have closely related structures and have the same 1-5/2-1 spin system, they show completely different magnetic interactions between the adjacent metal ions: ferromagnetic (Ni-II-Mn-II) and antiferromagnetic (Ni-II-Fe-III).
