The planar aromatic dianion 1 is formed by the selective cleavage of four PC(phenyl) bonds in octaphenyltetraphosphafulvalene with Li or K. The tetraphosphafulvalenes cannot be stacked to give charge‐transfer complexes because of the pyramidal environment at the P atoms; however, this is possible with dianion 1 . If, for example, 1 is allowed to react with [Cp(xylene)Fe](PF 6 ), each of the five‐membered rings is coordinated to a [CpFe] + fragment.
