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-
Robson and Okaw et al. Condensed a series of macrocyclic binuclear ligands and their binuclear complexes (a) with 2,6-diformyl-4-substituted phenols and appropriate polyamines, and reacted with binuclear transition metal complexes The spectral and magnetic properties were studied. However, up to now, there are no reports about the condensation of N-oxide-2,6-dicarboxypyridine and polyamine to form macrocyclic ligands and their complexes. In order to study the effect of different bridging atoms on the magnetic interaction between metals in the macrocyclic dinuclear system,
