4-Amino-3-methyl-benzoic acid-1,2-bis-(4-pyrid-yl)ethane (1/1).

In the crystal structure of the title 1:1 adduct, C(12)H(12)N(2)·C(8)H(9)NO(2), the 4-amino-3-methyl-benzoic acid mol-ecules and 1,2-bis-(4-pyrid-yl)ethane mol-ecules are linked by inter-molecular O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds, forming a two-dimensional supra-molecular network parallel to (001). In the 1,2-bis-(4-pyrid-yl)ethane mol-ecule, the two pyridine rings are twisted to each other by a dihedral angle of 12.12 (8)°. The non-H atoms of the 4-amino-3-methyl-benzoic acid mol-ecule are almost coplanar, the maximum atomic deviation being 0.029 (1) Å. Weak C-H⋯π inter-actions are present in the crystal structure.
