摘要：

The reactions between 2,4,6-tris(2-p ridyl)-1,3,5-triazine (tptz) and halogens (Br-2,I-2) or interhalogens (ICl, IBr) yielded different products isolated in the solid state. (Htptz(+))(Br-3(-)), (Htptz(+))(IBr2-), (H(3)tptz(3+)) (I3Br4-) (IBr2-)(2), and (H(3)tptz(3+))(ICl2-)(3) obtained from the reactions between tptz and Br-2, 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 (H(3)tptz(3+)) (I3Br4-)(IBr2-)(2) the first example of a planar I3Br4_ moiety can be observed. In the case of the reaction between tptz and I-2, the elemental analysis of the product indicates a 1:1 molar ratio between tptz and I-2, 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.
