title: 2-Amino-4-methyl-pyridinium trifluoro-acetate: a monoclinic polymorph.
abstract: 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.
