2-Amino-4-methyl­pyridinium trifluoro­acetate: a monoclinic polymorph

The title salt, C(6)H(9)N(2) (+)·C(2)F(3)O(2) (−), is a monoclinic polymorph of a previously reported structure [Hemamalini & Fun (2010). Acta Cryst. E66, o781–o782]. In the crystal structure, the cations and anions are linked by two different types of N—H⋯O hydrogen bonds, forming cation–anion...

Descripción
Sumario:The title salt, C(6)H(9)N(2) (+)·C(2)F(3)O(2) (−), is a monoclinic polymorph of a previously reported structure [Hemamalini & Fun (2010). Acta Cryst. E66, o781–o782]. In the crystal structure, the cations and anions are linked by two different types of N—H⋯O hydrogen bonds, forming cation–anion pairs. These pairs are hydrogen bonded to neighbouring pairs via another N—H⋯O hydrogen bonds involving an H atom of the NH(2) group and one of the O atoms of the COO(−) group into a chain extended along the b axis.
