2-Amino-4-methyl­pyridinium trifluoro­acetate

The asymmetric unit of the title compound, C(6)H(9)N(2) (+)·C(2)F(3)O(2) (−), contains two independent 2-amino-4-methyl­pyridinium cations and two independent trifluoro­acetate anions. The F atoms of both anions are disordered over two sets of sites, with site occupancies of 0.50 (3) and 0.50 (3) in...

description The asymmetric unit of the title compound, C(6)H(9)N(2) (+)·C(2)F(3)O(2) (−), contains two independent 2-amino-4-methyl­pyridinium cations and two independent trifluoro­acetate anions. The F atoms of both anions are disordered over two sets of sites, with site occupancies of 0.50 (3) and 0.50 (3) in one of the anions, and 0.756 (9) and 0.244 (9) in the other. In the crystal, the cations and anions are linked into chains along the b axis by N—H⋯O hydrogen bonds and these chains are cross-linked by C—H⋯O hydrogen bonds, forming a two-dimensional network lying parallel to (101). The crystal structure is further stabilized by π–π inter­actions between the pyridinium rings [centroid–centroid distances = 3.5842 (13) and 3.5665 (16) Å].
