Abstract
Two polymorphic crystal forms of the title compound, C12H13NO2S (systematic name: 6-methyl-N-phenyl-2,3-dihydro-1,4-oxathiine-5-carboxamide), were isolated from a truncated, (12 solvent), polymorph screen on pure lyophillized material. Crystals of form 1 were obtained from all solvents included in the screen with the exception of methanol. As isolated from acetonitrile the crystals are triclinic, space group P\overline{1} with Z′ = 2. Crystals of form 2, which were isolated from methanol only are monoclinic, space group I2/a with Z′ = 1. The crystal packing in both structures is dominated by the formation of infinite –NH...O hydrogen-bonded chains through the carboxamide core.
