In (S)-(+)-5-(3-bromo-4-isopropoxyphenyl)-5-methylimidazolidine-2,4-dione, C13H15BrN2O3, (I), the hydantoin groups are connected via intermolecular N-H. O hydrogen bonds, forming a terraced sheet structure. In the chloro analogue, (S)-(+)-5-(3-chloro-4-isopropoxyphenyl)-5-methylimidazolidine-2,4-dione, C13H15ClN2O3, (II), the intermolecular N-H. O hydrogen-bonding network forms a flat sheet. Comparison of the crystal structures reveals that (II) is more loosely packed than (I).
