Crystal structures of (S)-(+)-5-(3-bromo/chloro-4-isopropoxyphen­yl)-5-methyl­imidazolidine-2,4-dione

In (S)-(+)-5-(3-bromo-4-isopropoxyphen­yl)-5-methyl­imidazolidine-2,4-dione, C(13)H(15)BrN(2)O(3), (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-methyl­imidazoli...

Sumario:In (S)-(+)-5-(3-bromo-4-isopropoxyphen­yl)-5-methyl­imidazolidine-2,4-dione, C(13)H(15)BrN(2)O(3), (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, C(13)H(15)ClN(2)O(3), (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).
