A Z arrangement of substituents about the carboxylate C-O bond causes a syn positioning of the carbonyl O atom and the heterocyclic part of the title compound, C 18 H 15 NO 3 S. The carboxylate entity is inclined by À28.1 (3) to the phenyl group. The planes of the thiazol-2(3H)-thione subunit and th
