3-Amino­benzoic acid–1,2-bis­(4-pyrid­yl)ethane (1/1)

The asymmetric unit of the title compound, C(12)H(12)N(2)·C(7)H(7)NO(2), contains two 3-amino­benzoic acid mol­ecules and two 1,2-bis­(4-pyrid­yl)ethane mol­ecules. In the two 1,2-bis­(4-pyrid­yl)ethane mol­ecules, the dihedral angles between the pyridyl rings are 2.99 (9) and 46.78 (8)°. In the crystal, the mol­ecules associate through amine and carboxyl group N—H⋯O=C inter­actions between one of the 3-amino­benzoic acid mol­ecules and one of the 1,2-bis­(4-pyrid­yl)ethane mol­ecules, generating R (2) (2)(14) dimers, which are extended head-to-tail via amine and pyridine N—H⋯N hydrogen bonds. Inter­molecular O—H⋯N, N—H⋯O, N—H⋯N and C—H⋯O hydrogen bonding are observed in the crystal structure. C—H⋯π and π–π stacking inter­actions [centroid–centroid distance = 3.9985 (10) Å] are also present.
