2-Amino-4-methoxy-6-methylpyrimidin-1-ium trifluoroacetate

Abstract

In the title molecular salt, C6H10N3O+·C2F3O2−, the pyrimidinium cation is essentially planar, with a maximum deviation of 0.042 (3) Å for all non-H atoms. In the crystal, the cations and anions are linked via N—H...O hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R22(8) and R42(8) ring motifs. These motifs are further linked through a pair of C—H...O hydrogen bonds into a supramolecular tape along the [101] direction.
