organic compounds
The cation of the title salt, C24H25N52+·2ClO4-, contains a tris(2-pyridylmethyl)amine core in which one of the pyridine N atoms is protonated and a second pyridine N atom forms an additional C-N bond to another 2-pyridylmethyl group, resulting in a second pyridinium center. The protonated pyridinium hydrogen bonds to a pyridine ring of a neighboring dication. The hydrogen-bonded H atom is disordered between the two N atoms.
