2-(Pyridin-2-yl)pyridinium trifluoromethanesulfonate
Although in the title salt, C10H9N2+·CF3SO3−, the C—C and C—N bond lengths within the aromatic rings are normal, there is a considerable difference in the C—N—C angles at the protonated and unprotonated N atoms, viz. 123.42 (10) and 117.10 (11)°, respectively. Bifurcated N—H...X (X = N or O) hydroge...

| description | Although in the title salt, C10H9N2+·CF3SO3−, the C—C and C—N bond lengths within the aromatic rings are normal, there is a considerable difference in the C—N—C angles at the protonated and unprotonated N atoms, viz. 123.42 (10) and 117.10 (11)°, respectively. Bifurcated N—H...X (X = N or O) hydrogen bonds form within the cation and between cation and anion. As a result, the cation exists in a cis conformation in the solid state. An obvious π–π contact is also present between the non-protonated pyridyl rings of neighbouring cations. |
