Structure of S-methyl 5-methylpyrazine-2-carbothioate. (a) Original structure. (b) The same structure translated by b/2. (c) Once again, the same structure translated by (a + b)/2. These translations belong not to the space-group symmetry of the crystal but to its Euclidean normalizer and produce alternative but equivalent descriptions of the structure.
