چکیده
In the title mol-ecule, C(13)H(16)N(2)O(2), the cyclo-hexyl-idene ring adopts a chair conformation. The intra-molecular N-H⋯O hydrogen bond influences the mol-ecular conformation: the benzene ring and the mean plane of the central C(O)NHN fragment form a dihedral angle of 4.9 (1) Å. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains propagated along [001].

In the title compound, C16H18ClN3O, the cyclo-hexane ring adopts a distorted chair conformation. In the crystal, pairs of mol-ecules are linked by N-H⋯O hydrogen bonds into inversion dimers, forming R 2 (2)(10) ring motifs. These dimers are connected through C-H⋯N hydrogen bonds into chains along the a axis, forming layers parallel to (101).

The conformation of the title compound, C14H19N3S, is partially determined by an intra-molecular N-H⋯N hydro-gen-bond inter-action, although the N-H⋯N angle of 108° is quite small. The cyclo-hexyl-idene ring has a chair conformation and its mean plane is inclined to the benzene ring by 46.30 (8)°. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers, ...

The title compound C(8)H(15)N(3)S has two mol-ecules in the asymmetric unit in which cis-trans isomerism is exhibited around the N(NH)C=S bonds. The cyclo-hexyl rings in both mol-ecules adopt a chair conformation. In the crystal, N-H⋯S hydrogen bonding produces dimers, which are inter-connected through further N-H⋯S hydrogen bonds, forming chains along the b-axis direction.

In the title compound, C(14)H(19)N(3)S, the cyclo-hexane ring has a chair conformation. The almost planar amino-thio-urea unit (r.m.s. deviation = 0.0062 Å) is aligned at a dihedral angle of 45.23 (8)° with respect to the benzene ring. Inter-molecular N-H⋯N and N-H⋯S hydrogen bonding stabilizes the crystal structure.
