【 摘 要 】

In the crystal structure of the title co-crystal, C25H32N4O2·C8H6O4, isophthalic acid and [propane-1,3-diylbis(piperidine-4,1-diyl)]bis(pyridin-4-ylmethanone) molecules are connected into supramolecular chains aligned along the c axis by O—H...N hydrogen bonding. These aggregate into supramolecular layers oriented parallel to the ac plane by C—H...O interactions. These layers then stack in an ABCD pattern along the b-axis direction by additional C—H...O interactions to give the full three-dimensional crystal structure. The central chain in the dipyridylamide molecule has an anti–gauche conformation.
