Abstract: In the crystal of the title compound, C6H9N3·C6H8O2, the 2-amino-4,6-dimethylpyrimidine and sorbic acid molecules are linked through N-HO and O-HN hydrogen bonds, which generate a cyclic bimolecular heterosynthon with an R22(8) graph-set motif. Further, two inversion-related pyrimidine molecules are base-paired via a pair of N-HN hydrogen bonds, forming a cyclic bimolecular homosynthon with a graph-set of R22(8). A discrete hetero tetrameric supramolecular unit along the b axis is formed by the fusion of two heterosynthons and one homosynthon. An aromatic - interaction [centroid-centroid distance = 3.7945 (16) Å] is observed between these tetrameric units.
