合成了一种新的双亚氨基氮氧自由基取代间苯二酚3 H，它具有两个金属结合位点，分别与两对酚阴离子和亚氨基氮原子结合。粉末状的3 H样品显示出两个亚氨基氮氧化合物之间通过间苯桥的分子内铁磁相互作用（J/kB=+5K）和弱的分子间反铁磁相互作用（J/kB=-0.9K）。研究了~ 3 H与醋酸铜在甲醇氨溶液中的反应，得到了一种难溶的铜配合物，该配合物在较高温度（298- 55 K）下表现出铁磁性。
A novel bis(imino nitroxide)-substituted resorcinol 3H, that has two metal-binding sites with two pairs of the phenolate anion and the imino nitrogen atom, was prepared. The powdered sample of 3H showed an intramolecular ferromagnetic interaction (J/kB=+5K) between two (imino nitroxide)s through a m-phenylene bridge and a weak intermolecular antiferromagnetic interaction (J/kB=−0.9K). The reaction of 3H with copper acetate in methanolic ammonia was examined to give a hardly soluble Cu-complex that exhibited ferromagnetic behavior in relatively high temperatures (298–55K).
