4,4′-Bipyridine–3-(thiophen-3-yl)acrylic acid (1/2)

Abstract

In the title 1/2 adduct, C10H8N2·2C7H6O2S, the dihedral angle between the pyridine rings is 18.41 (11)°. In the thiopheneacrylic acid molecules, the dihedral angles between the respective thiophene 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.
