4-Amino­benzoic acid–4,4′-(propane-1,3-diyl)dipyridine (1/1)

In the crystal structure of the title compound, C(13)H(14)N(2)·C(7)H(7)NO(2), the 4,4′-trimethyl­ene-dipyridine (TMDP) mol­ecule displays an approximately planar structure, the maximum atomic deviation excluding H atoms being 0.118 (2) Å and the dihedral angle between the pyridine rings 4.59 (10)°. The TMDP and 4-amino­benzoic acid (ABA) mol­ecules are linked by O—H⋯N and N—H⋯N hydrogen bonding, while ABA mol­ecules are linked by O—H⋯O hydrogen bonding. C—H⋯π interactions are also observed between the methyl­ene groups of TMDP mol­ecules and the benzene rings of ABA mol­ecules.
