Abstract: The title compound, (C₂₇H₂₆P₃)[AlCl₄]·CH₂Cl₂, was isolated from a mixture containing the triphosphenium ion and its protonated derivative. The central cation ring is non-planar, as in the analogous hexachlorostannate (though the structures are not isomorphous), and the P-P distances are intermediate between those typical for single and double bonds.
