Reaction of bis(peri-substituted) triphosphine iPr(AcenapPiPr2)2 (Acenap = acenaphthene-5,6-diyl) with iodine, followed by hydrolysis, afforded ionic species with [iPr(AcenapP(O)iPr2)2] dication, containing P-O-P-O-P motif, balanced by triiodide anions. The new species were fully characterized including single crystal X-ray diffraction. Formation of the unusual double bridged motif is likely a result of crowding in the peri-region.
