Theoretical and experimental study of the protonated 2,4,6-tri(2-pyridyl)-1,3,5-triazine [TPTZH 2 ] 2+

The reaction between 2,4,6-tri(2-pyridyl)-1,3,5-triazine (TPTZ) and sulfuric acid in the presence of NH4PF6 yielded crystals of [TPTZH2](PF6)2·H2O, characterized by spectroscopic methods and single-crystal X-ray diffraction. The structural data indicat
