A series of metal‐free compounds, ie, planar triprotonated triazine, triazineH 3 Cl(PF 6 ) 2 ( 1 ), planar triprotonated triazineH 3 Br(PF 6 ) 2 ( 2 ), and nonplanar monoprotonated triazineHPF 6 ( 3 ), were prepared. Abbreviations used are triazine = tri‐2‐pyridyltriazine. Ruthenium complexes [RuCl(bpy)(L)](PF 6 ), [RuCl(bpy)(L)](PF 6 ) 2 , and [Ru(L) 2 ](PF 6 ) 2 were also prepared, where bpy is 2,2′‐bipyridine and L's are triazine ( 4 ) and monoprotonated triazine ( 5 ), respectively. Ruthenium complexes [Ru(triazine) 2 ](PF 6 ) 2 ( 6 ) were also prepared and crystallized. The X‐ray crystal structures of the 3 compounds 1 , 2 , and 3 and the complex 6 were determined. They were also characterized by electrospray ionization mass spectrometry, UV‐vis spectroscopy, and density functional theory calculations.
