RESUMO
In the title co-crystal, C25H32N4O2·C14H10O5, mol-ecules are connected into supra-molecular chains aligned along [102] by O-Hâ¯N hydrogen bonding. These aggregate into supra-molecular layers oriented parallel to (20-1) by C-Hâ¯O inter-actions. These layers then stack in an ABAB pattern along the c crystal direction to give the full three-dimensional crystal structure. The central chain in the dipyridylamide has an anti-anti conformation. The dihedral angle between the aromatic ring planes is 29.96â (3)°. Disorder is noted in some of the residues in the structure and this is manifested in two coplanar dispositions of one statistically disordered carb-oxy-lic acid group.
