2，4，6-三(2-吡啶基)-1，3，5-三嗪(Tptz)与卤素(Br2，I2)或卤间化合物(ICl，IBr)反应生成不同的固态分离产物。用单晶X射线衍射法和傅立叶变换拉曼光谱对Tptz与Br2、IBR和ICL反应得到的(Htptz+)(Br3-)、(Htptz3+)(IBr2-)、(H3tptz3+)(I3Br4-)(IBr2-)2和(H3tptz3+)(ICl2-)3进行了表征。所有化合物都是含有质子化给体的盐类，被各种复杂性的多卤化物阴离子抵消。具体地，在(H3tptz3+)(I3Br4-)(IBr2-)2中可以观察到平面I3Br4-部分的第一个例子。在TPTZ与I2反应的情况下，产物的元素分析表明TPTZ与I2的摩尔比为1：1，但FT-拉曼光谱与简单加合物的形成不一致，清楚地表明二碘和对称的三碘同时存在。(Wiley-VCH Verlag GmbH&Co.KGaA，69451温海姆，德国，2008年)
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 complexity. In particular, in (H3tptz3+)(I3Br4–)(IBr2–)2 the first example of a planar I3Br4– moiety can be observed. In the case of the reaction between tptz and I2, the elemental analysis of the product indicates a 1:1 molar ratio between tptz and I2, but the FT-Raman spectrum is not consistent with the formation of a simple adduct, clearly indicating the simultaneous presence of diiodine and symmetric triiodide.
