title: 4-Amino-benzoic acid-4,4'-(propane-1,3-diyl)dipyridine (1/1).
abstract: In the crystal structure of the title compound, C(13)H(14)N(2)·C(7)H(7)NO(2), the 4,4'-trimethyl-ene-dipyridine (TMDP) mol-ecule 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-amino-benzoic acid (ABA) mol-ecules are linked by O-H⋯N and N-H⋯N hydrogen bonding, while ABA mol-ecules are linked by O-H⋯O hydrogen bonding. C-H⋯π interactions are also observed between the methyl-ene groups of TMDP mol-ecules and the benzene rings of ABA mol-ecules.
