本文报道了一种新的一维链状配合物Mn（hfac）（2）-桥联[2-（3-吡啶基）合成了[（硝酰基氮氧自由基）Mn（hfac）（2）]（2），并对其结构和磁性进行了表征;该配合物在三个Mn（ii）原子和两个硝酰基氮氧化物之间表现出大的反铁磁相互作用J（1）=-185K，得到S=13/2自旋单元和小的铁磁相互作用J（在低温（50-1.9 K）下，这些自旋单元之间的3 π ′ =+0.02 K，与模型化合物的理论分析相容。
A new one-dimensional chain complex, Mn(hfac)(2)-bridged [2-(3-pyridyl)(nitronyl nitroxide)Mn(hfac)(2)](2), was prepared and its structure and magnetic properties were elucidated; the complex exhibited a large antiferromagnetic interaction of J(1)=-185 K between the three Mn(ii) atoms and the two nitronyl nitroxides to give S=13/2 spin units and a small ferromagnetic interaction of J(3)'=+0.02 K between these spin units at low temperatures (50-1.9 K), compatible with the theoretical analysis for model compounds.
