چکیده
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.

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, ...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(13)N(3)OS, which was obtained from a condensation reaction of N-(p-tol-yl)hydrazinecarbothio-amide and furfural. The dihedral angles between the mean planes of the tolyl ring and the (furan-2-yl-methyl-ene)hydrazine unit are 39.83 (8) and 48.95 (7)° in the two mol-ecules. The mol-ecules both exhibit an E c...

The asymmetric unit of the title compound, C10H17N3S, consists of three symmetry-independent mol-ecules with distinctly different conformations, as indicated for example by the C-N-C-C torsion angles of -155.9 (3), 89.9 (3) and 81.1 (4)° along the bond between thio-urea and allyl units. In the crystal, mol-ecules are connected via N-H⋯N and N-H⋯S hydrogen bonds into chains extending along [110]...
