In the highly symmetrical environment of the P<sup>V</sup> center in the cation [P{P(o-C<sub>6</sub> H<sub>4</sub> O)<sub>2</sub> Ph}<sub>2</sub> ]<sup>+</sup> of 1 the two P<sup>V</sup> -P<sup>III</sup> bonds are relatively short (2.2023(10) Å) for compounds of this type. Compound 1 was obtained from the reaction of PCl<sub>5</sub> with two equivalents of [(o-OSiMe<sub>3</sub> )C<sub>6</sub> H<sub>4</sub> ]<sub>2</sub> PPh.
