Abstract: The title 2:1 co-crystal, 2C12H10N2·C8H6O4, crystallizes with one molecule of 4-[(E)-2-(pyridin-2-yl)ethenyl]pyridine (A) and one half-molecule of terephthalic acid (B) in the asymmetric unit. In the crystal, the components are linked through heterodimeric COOHNpyridine synthons, forming linear aggregates of composition -A-B-A-B-. Further linkage through weak C-HO and C-H interactions gives two-dimensional hydrogen-bonded undulating sheets propagating in the  and  directions. These layers are connected through additional weak C-HO contacts, forming a three-dimensional structure.
