在结晶状态下，具有铁磁性相互作用的持久性有机自由基很少。一个例子是晶体1，3，5-己三炔在1位带有[4-氯-3-(N-叔丁基-N-氧氨基)苯基]取代基。这已经被研究并与带有相同取代基的晶体1，3-丁二炔(见图)进行了比较，后者在低温下表现出反铁磁相互作用。
Persistent organic radicals with a ferromagnetic interactionin the crystalline state are few and far between. One example is crystalline 1,3,5‐hexatriyne carrying a [4‐chloro‐3‐(N‐tert‐butyl‐N‐oxyamino)‐phenyl] substituent at position 1. This has been studied and compared with crystalline 1,3‐butadiyne (see Figure) carrying the same substituent, which, in contrast, exhibits antiferromagnetic interactions at cryogenic temperatures.
