Abstract
In the title 1/2 adduct, C 10H 8N 2· 2C 7H 6O 2S, the dihedral angle between the pyridine rings is 18.41 (11)°. In the thiopheneacrylic acid molecules, 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 interactions, forming units of two 3-thiopheneacrylic acid molecules and one 4,4′-bipyridine molecule.
