title: 2-(2-Pyridylsulfan-yl)acetic acid.
abstract: All non-H atoms of the title compound, C(7)H(7)NO(2)S, lie on a crystallographic mirror plane, with the two methyl-ene H atoms bis-ected by this plane. The crystal packing is characterized by inter-molecular C-H⋯O and O-H⋯N contacts, which link the mol-ecules into infinite zigzag chains parallel to [010].
