Abstract: In the title compound, C₆H₉N₃·2C₉H₈O₂, an aminopyrimidine-cinnamic acid 1:2 cocrystal, the 2-amino-4,6-dimethylpyrimidine molecule forms two eight-membered hydrogen-bonded rings [R₂²(8) motif] with the carboxylic acid groups from two independent cinnamic acid molecules via N-HO and O-HN hydrogen bonds. The cinnamic acid molecules are linked by C-HO hydrogen bonds to form chains along two axes.
