The title compound, C(6)H(6)N(2)O(2)S, is a new polymorphic form of 2-(pyrimidin-2-ylsulfan-yl)acetic acid. Unlike the previous orthorhombic polymorph [Pan & Chen (2009 ▶) Acta Cryst. E65, o652], the mol-ecules are not planar: the aromatic ring makes an angle of 80.67 (17)° with the carboxyl plane. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds into chains along [02].
标题化合物C(6)H(6)N(2)O(2)S是2-(嘧啶-2-基硫烷基)乙酸的一种新的多晶型物。与之前的正交多晶型物[Pan & Chen (2009 ▶) Acta Cryst. E65, o652]不同，分子不是平面的：芳环与羧基平面的夹角为80.67 (17)°。在晶体中，分子通过O—H⋯N氢键沿[02]连接成链。
