已分离出假定的反三环己基的四磷苯类似物，苯的单线态双价异构体。该三环衍生物具有单电子磷-磷键，这是由两个二磷烯基自由基之间的 pi*-pi* 相互作用产生的。这种单电子键可能在磷化学中发挥更广泛的作用。
A tetraphosphabenzene analog of the postulated anti-tricyclohexylene, a singlet biradical valence isomer of benzene, has been isolated. The tricyclic derivative features one-electron phosphorus-phosphorus bonds, which result from the pi*-pi* interaction between two diphosphirenyl radicals. Such one-electron bonds may play a wider role in phosphorus chemistry.
