 Title    Untersuchungen an Polyhalogeniden, XX [1]  
 Abstract    Darstellung und Kristallstruktur von Tetra(m ethyltriphenylphosphonium)docosaiodid (M ePh3P)4I22 Studies of Polyhalides, XX [1] Preparation and Crystal Structure of Tetra(methyltriphenylphosphonium)docosaiodide (M ePh3P)4I22 The new compound (M ePh3P)4I22 has been prepared by the reaction of Ph3MePI with iodine in a mixture of methanol and dichloromethane. It crystallizes in the triclinic space group P i with a = 1018.4(3), b = 1333.0(4), c = 2042.9(6) pm, a = 88.56(2), ß = 78.05(2), y = 76.03(2)° and Z = 1. The crystal structure has been refined to RF = 0.0487 for 5525 reflections. It may be described as a layer-like packing of cations [CH3(C6H3)3P]+ and anions I224-di­ vided in one I)22-and two I5_ groups. The central Ii22-anion with point symmetry Q consist­ ing of two L-shaped pentaiodide groups and a bridging iodine molecule is completed by two further end-on bonded pentaiodide ions with a rather short distance o f 366.7(2) pm to the weakly bonded and nearly isolated docosaiodide ion.
