Despite the first examples being isolated more than two decades ago, little is known about the redox chemistry of stable phosphacyclic biradicaloids. Here, we demonstrate that a biradicaloid featuring a diphosphaindenyl backbone is able to undergo both oxidation and reduction reactions. One-electron oxidation results in the formation of a dicationic cage compound structurally related to an isomer of hypostrophene (C10H10). Reduction of PPIPh with [Co2(CO)8] results in the formation of the bimetallic complex 2, which contains a bis(benzodiphosphole) ligand.
