title: 2-(4-Hydroxy-phen-yl)acetic acid-4,4'-bipyridine (1/1).
abstract: In the acid mol-ecule of the title complex, C(10)H(8)N(2)·C(8)H(8)O(3), the acetyl C-C-C-O torsion angle is -32.1 (3)°, and in the mol-ecule of the base, the dihedral angle between the two pyridine rings is 23.41 (10)°. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link the acid and the base mol-ecules into a one-dimensional triple-helix framework extended along the b axis.
