Reaction of methylene‐ and ethylene‐bridged bis‐imidazolium salts with white phosphorus in the presence of KOtBu furnished moderate yields of tricyclic bis‐imidazolio‐phosphanide halides. Further oxidation of the products with one equivalent of I2 gave bis‐imidazolio‐diiodophosphoranide iodides. All newly prepared compounds were characterized by analytical and spectroscopic data and single‐crystal XRD studies. DFT calculations provide evidence for substantial stabilization of cyclic bis‐imidazolio‐phosphanide cations by π‐conjugation effects and suggest describing the bis‐imidazolio‐diiodophosphoranide cations as charge‐transfer complexes of dicationic iodophosphines with iodide.
