Yagi, Yoshiharu published the artcileNew polyhalide complex ions, Recommanded Product: Pyridine Iodochloride complex, the publication is Inorganic and Nuclear Chemistry Letters (1965), 1(1), 21-4, database is CAplus.
Polyhalide complexes of the type A.HICl2.ICl (A = organic base) were prepared by dissolving a A.HICl2 complex in 1,2-dichloroethane, adding a 4-5 fold excess of ICl, and diluting the resulting solution with CCl4. The compounds prepared and their m.ps. are: 2,2′-bp.HICl2.ICl (65-7°) (bp = bipyridine); 4,4′-Me3-2,2′-bp.HICl2.ICl (57-9°); 2,2′-bq.HICl2.ICl (139-40°) (bq = biquinoline); 1,10-phen.HICl2.ICl (96.5-7.5°) (phen = phenanthroline); 2,9-Me2-1,10-phen.HICl2.ICl (97-8°); 4,7-Me2-1,10-phen.HICl2.ICl (114-15°); py.HICl2.ICl (85-6°); 2,6-lu.HICl2.ICl (lu = lutidine); and Me4N.ICl2.ICl. The last 2 were red-orange oils which, on cooling, solidified to glasses; the others precipitated as orange microcrystalline powders. All are quite stable at room temperature They decomposed slowly by atm. moisture. They are soluble in many organic solvents (except CCl4), dissociating to A.HICl2 and ICl. They lose a mole of ICl on heating to ∼100°. Ir data seems to indicate the I2Cl3– ion.
