title: Hydrogen-bonding patterns in rac-1-acetyl-5-methyl-2-thioxoimidazolidin-4-one.
abstract: In the title compound, C(6)H(8)N(2)O(2)S, also known as N-acetyl-2-thiohydantoin-alanine, the molecules are joined by N-H...O hydrogen bonds, forming centrosymmetric R2(2)(8) dimers; these dimers are linked by C-H...O interactions to form R2(2)(10) rings, thus forming C2(2)(10) chains that run along the [101] direction.
