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(19)H(25)N(3)O(5), the benzene ring is not coplanar with the amide group [dihedral angle = 61.90 (5)°]. The cyclo-hexyl rings are in chair conformations. There is a strong inter-molecular inter-action between the C=O group of the amide group and the nitro group of an adjoining mol-ecule, with a short O⋯N distance of 2.7862 (17) Å. In the crystal, C-H⋯O inter-actions occu...

In the title compound, [Hg(CN)(2)(C(6)H(13)N)(2)], the Hg(II) ion adopts an extremely distorted HgC(2)N(2) tetra-hedral coordination. The crystal packing is influenced by weak N-H⋯N hydrogen bonds between the amino groups and the cyanide N atoms, resulting in chains of mol-ecules propagating in [110]. Both cyclo-hexyl-amine mol-ecules adopt chair conformations.

In the title polymeric complex, [Sn(C(6)H(5))(3)(C(14)H(16)NO(3))](n), adjacent triphenyl-tin cations are bridged by the N-cyclo-hexyl-phthalamate anion through the carboxyl-ate and carbonyl O atoms, forming a helical chain running along the b axis. The amide N atom is a hydrogen-bond donor to the uncoordinated carboxyl-ate O atom. The geometry at the five-coordinate Sn atom is trans-C(3)SnO(2)...

In the title compound, C(15)H(17)ClN(2)O(4)S, the atoms in the hydantoin ring are coplanar (r.m.s. deviation = 0.006 Å). The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds which link the mol-ecules into centrosymmetric dimers. The dihedral angle subtended by the 4-chloro-phenyl group with the plane passing through the hydantoin unit is 82.98 (4)°. The cyclo-hexyl ring a...

The title compound, C(10)H(9)NO(4), was obtained serendipitously during the preparation of benzyl cyclo-hexyl-carbamate. The mol-ecule consists of two approximately planar parts, the nitro-phenyl ring and the rest of the non-H atoms, with a dihedral angle of 55.05 (6)° between the two segments. The crystal structure is stabilized by weak C-H⋯O inter-actions and π stacking [3.753 (1) Å] along th...

The environment at the Sn(IV) atom in the title compound, [Sn(C(6)H(11))(2)(C(18)H(11)BrN(2)O(3))], is distorted trigonal-bipyramidal, with the two cyclo-hexyl groups and the imino N atom forming the equatorial plane. The axial O-Sn-O angle is 155.97 (9)°. The presence of an intra-molecular O-H⋯N hydrogen bond in the Schiff base ligand helps to stabilize the overall structure.

In the title compound, C(21)H(21)FO(3)S, the cyclo-hexyl ring adopts a chair conformation. The 4-fluoro-phenyl ring makes a dihedral angle of 77.71 (4)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked through inter-molecular C-H⋯O hydrogen bonds and aromatic π-π inter-actions between the furan rings of neighbouring mol-ecules [centroid-centroid distance = 3...

The crystal structure of the title compound, C(15)H(17)BrN(2)O(4)S, is stabilized by inter-molecular N-H⋯O hydrogen bonds which link the mol-ecules into centrosymmetric dimers. The dihedral angle subtended by the 4-bromo-phenyl group with the mean plane passing through the hydantoin unit is 83.29 (5)°. The cyclo-hexyl group adopts an ideal chair conformation with the methyl group in an equatori...

A new tetra-dentate chiral Schiff base ligand, C(16)H(26)N(2)O(2), has been synthesized by the reaction of acetyl-acetone with (1R,2R)-(-)-1,2-diamino-cyclo-hexane. Both of the mol-ecules in the asymmetric unit are of the same chirality (R configuration), since the absolute configuration was determined by the starting reagent (1R,2R)-(-)-1,2-diamino-cyclo-hexane. The six-membered cyclo-hexane r...
