Deskripsi
In the title 1:1 co-crystal, C10H8N2·C15H12O5, strong intermolecular O—H...N hydrogen bonds link alternating molecules of 4,4′-(hydroxymethylene)dibenzoic acid and 4,4′-bipyridyl into zigzag chains in [501]. The crystal packing also exhibits π–π interactions between the 4,4′-bipyridyl rings of neighbouring chains [centroid–centroid distance = 3.608 (3) Å] and weak C—H...O hydrogen bonds.
