In the title compound, C15H17ClN2O4S, the atoms in the hydantoin ring are coplanar (r.m.s. deviation = 0.006 Å). The crystal structure is stabilized by intermolecular N-H...O hydrogen bonds which link the molecules into centrosymmetric dimers. The dihedral angle subtended by the 4-chlorophenyl group with the plane passing through the hydantoin unit is 82.98 (4)°. The cyclohexyl ring adopts an ideal chair conformation. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.002 Å; R factor = 0.030; wR factor = 0.081; data-to-parameter ratio = 15.0.

The dihedral angle subtended by the 4-bromophenyl group with the mean plane passing through the hydantoin unit is 83.29 (5)°. The cyclohexyl group adopts an ideal chair conformation with the methyl group in an equatorial position. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.003 Å; R factor = 0.030; wR factor = 0.070; data-to-parameter ratio = 16.8.
Adamantane-1-thioamide
(2009)
The title compound, C11H17NS, is an important intermediate for the synthesis of biologically active adamantlythiazolo-oxadiazoles. The adamantyl residue is disordered about a twofold rotation axis over two sites with site-occupation factors of 0.817 (3) and 0.183 (3). The crystal structure is stabilized by intermolecular N-H...S hydrogen-bonding interactions. Key indicators: single-crystal X-ray study; T = 173 K; mean &963;(C–C) = 0.002 Å; disorder in main residue; R factor = 0.038; wR factor = 0.103; data-to-parameter ratio = 12.3.
