rac-1-Acetyl-5-benzyl-2-thioxoimidazolidin-4-one.

In the title compound, C(12)H(12)N(2)O(2)S, the mol-ecules have a wing-like conformation, with a distance of 3.797 (2) Šbetween the centroids of the five- and six-membered rings. In the crystal structure, mol-ecules are linked by N-H⋯O hydrogen bonds, forming infinite one-dimensional zigzag chains, running along [001], with a C(4) graph-set motif.
