2-[(1-Oxidopyridin-4-yl)sulfanyl]benzoic acid

Abstract

In the title compound, C12H9NO3S, the dihedral angle between the pyridine and benzene rings is 83.93 (7)°. In the crystal, pairs of O—H...O hydrogen bonds link the molecules, forming inversion dimers with graph-set notation R22(22). These dimers are in turn linked by weak C—H...O hydrogen bonds along [100], forming R22(8) rings.
