Description
Summary:In the title compound, C16H14ClN3O3S, the thiazine ring adopts a sofa (half-chair) conformation, with an r.m.s. deviation from the mean plane of 0.23 Å. The S atom and S-bonded C atom exhibit the maximum deviations from the thiazine mean plane [−0.3976 (12) and 0.3179 (14) Å, respectively]. The conformations around the double bonds in the R2C=N—N=CHR unit are Z and E. An intramolecular O—H...N hydrogen bond with the hydroxy group as donor generates an S(6) ring motif. In the crystal, pairs of weak C—H...O interactions connect the molecules, forming inversion dimers.
