2, 2':6', 2''-Terpyridinium Trifluoromethane-sulfonate, /terpyH/(CF_3SO_3)

In the title compound, C_15H_12N_3^+ˇCF_3O_3S^-, one terminal pyridine ring of the terpyridinium cation is protonated and forms an intramolecular N-HˇˇˇN hydrogen bond of 2.646 (4) Ĺ which stabilizes the cis, trans conformation in contrast to the trans, trans geometry of free terpyridine. An N-HˇˇˇO hydrogen bond of 2.817 (5) Ĺ connects the terpyridinium cations and the trifluoromethanesulfonate anions
