Monoclinic polymorph of 2-(pyrimidin-2-ylsulfanyl)acetic acid

M. Ramos Silva, P. S. Pereira Silva, C. Yuste and J. A. Paixão

Abstract: The title compound, C₆H₆N₂O₂S, is a new polymorphic form of 2-(pyrimidin-2-ylsulfanyl)acetic acid. Unlike the previous orthorhombic polymorph [Pan & Chen (2009) Acta Cryst. E65, o652], the molecules are not planar: the aromatic ring makes an angle of 80.67 (17)° with the carboxyl plane. In the crystal, molecules are linked by O-HN hydrogen bonds into chains along [ $\\overline{1}$ 02].
