Reactions of Halogens/Interhalogens with Polypyridyl Substrates: The Case of 2,4,6‐Tris(2‐pyridyl)‐1,3,5‐triazine

Abstract: The reactions between 2,4,6‐tris(2‐pyridyl)‐1,3,5‐triazine (tptz) and halogens (Br2, I2) or interhalogens (ICl, IBr) yielded different products isolated in the solid state. (Htptz+)(Br3–), (Htptz+)(IBr2–), (H3tptz3+)(I3Br4–)(IBr2–)2, and (H3tptz3+)(ICl2–)3, obtained from the reactions between tptz and Br2, IBr, and ICl, were characterized by single‐crystal X‐ray diffraction and FT‐Raman spectroscopy. All compounds are salts containing the protonated donor counterbalanced by polyhalide anions of various complex… Show more

“…A rich chemistry of transition metal-tptz compounds has developed in recent years including their applications in supramolecular chemistry, electrochemistry and photophysics [42][43][44][45]. However, hydrolysis of tptz to bis-(2-pyridylcarbonyl)amide anion has been reported in the presence of Rh III in aqueous-alcohol solution [46,47].…”
