双核Cu(Ⅱ)、Ni(Ⅱ)与N-氧化-2,6-二甲酰吡啶Schiff碱大环配合物的合成和表征

Synthesis and Characterization of Binuclear Complexes of Cu(Ⅱ) , Ni(Ⅱ) with Schiff Bases Macrocyclic Ligand Derived form N-Oxide-2,6-Diformylpyridine and 1,3-Propanediamine

Robson和Okaw等用2,6-二甲酰-4-取代的酚和合适的多胺缩合成了一系列的大环双核配体及其双核配合物(a),并对双核过渡金属配合物的光谱和磁性进行了研究。但迄今为止,国内外尚未见到有关N-氧化-2,6-二甲酰吡啶和多胺缩合生成大环配体及其配合物的报道。为研究大环双核体系中不同桥连原子对金属间磁相互作用的影响,我们首次以N-氧化-

The title complexes, Cu2L(ClO4)C2H5OH·H2O, Ni2L(ClO4)·4H2O(L is the macrocyclic ligand) were synthesized from N-oxide-2, 6-diformylpyridine and Ⅰ, 3-propanediamine by using Cu(Ⅱ) ions and Ni(Ⅱ)ions as the templating metal ions. The new compounds were characterized by elementary analysis, 1R, ESR and magnetism.
