N-Cyclo-hexyl-N′-(4-nitro-benzo-yl)thiourea

In the title compound, C14H17N3O 3S, the nitro group is twisted slightly by 2.6 (3)° from the benzene ring plane and the thio-ureido group makes a dihedral angle of 52.06 (4)° with the benzene ring. The cyclohexyl ring displays a chair conformation. An intramolecular N - H⋯O inter-action is present. In the crystal, intermolecular N - H⋯S hydrogen bonds link the molecules into centrosymmetric dimers. π-π interactions between inversion-related benzene rings (centroid-centroid distance = 4.044 Å) and C - H⋯π interactions (H⋯centroid distance = 3.116 Å) between one methylene cyclohexyl H atom and the benzene ring are also present.Department of Applied Biology and Chemical Technolog
