title: 4,4'-Bipyridine-3-(thio-phen-3-yl)acrylic acid (1/2).
abstract: In the title 1/2 adduct, C(10)H(8)N(2)·2C(7)H(6)O(2)S, the dihedral angle between the pyridine rings is 18.41 (11)°. In the thio-phene-acrylic acid mol-ecules, the dihedral angles between the respective thio-phene and acrylic acid units are 5.52 (17)° and 23.92 (9)°. In the crystal, the components are linked via O-H⋯N hydrogen-bonding inter-actions, forming units of two 3-thio-phene-acrylic acid mol-ecules and one 4,4'-bipyridine mol-ecule.
