In the title compound, C(13)H(14)N(2)·C(14)H(10)O(5), a 1:1 cocrystal of 1,3-di-4-pyridylpropane (bpp) and 4,4'-oxydibenzoic acid (H(2)oba), the dihedral angle between the two benzene rings of the flexible H(2)oba mol-ecule is 57.07 (1)°; the two pyridine rings of bpp make a dihedral angle of 27.52 (1)°. Strong inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into chains, which are then linked into a three-dimensional network through inter-molecular C-H⋯O and π-π stacking inter-actions [centroid-centroid distance = 3.7838 (3) Å].
