Keywords: | single-crystal X-ray study; T = 293 K; mean (C–C) = 0.004 A°; R factor = 0.054; wR factor = 0.133; data-to-parameter ratio = 16.9 | Issue Date: | 12-Jan-2011 | Publisher: | International Union of Crystallography | Project: | PTDC/FIS/102284/2008 | Serial title, monograph or event: | Acta Crystallographica Section E: Structure Reports Online | Volume: | 67 | Issue: | Pt 2 | Abstract: | 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]. | URI: | http://hdl.handle.net/10316/109982 | ISSN: | 1600-5368 | DOI: | 10.1107/S1600536811000651 | Rights: | openAccess |
