| Summary: | There are two independent molecules in the asymmetric unit of the title compound, C12H12N2O3S. With the exception of the methylene groups, a mean plane fitted through all non-H atoms of each molecule has an r.m.s. deviation of 0.035 Å for one molecule and 0.120 Å for the second. In one of the independent molecules, the methylene groups was refined using a disorder model with an occupancy ratio of 0.53:0.47 (14). Each molecule features an intramolecular O—H...O hydrogen bond, which generates an S(7) ring. |
