In the title compound, C(21)H(21)N(3)O(4)S, the cyclo-hexane ring adopts a chair conformation. The nitro and methyl-phenyl groups are all coplanar with the indole ring system. Intra-molecular N-H⋯O and C-H⋯S hydrogen bonds generate S(6) ring motifs. The mol-ecules form R(2) (2)(20) centrosymmetric dimers via inter-molecular C-H⋯O hydrogen bonds. A short O⋯O contact [2.842 (2) Å] is observed in ...

In the title compound, C(21)H(28)O(3)S, the benzofuran unit is essentially planar, with a mean deviation of 0.016 (1) Å from the least-squares plane defined by the nine constituent atoms. Both cyclo-hexane rings adopt chair conformations.

The title compound, C(29)H(28)N(2)O(3), displays anti-depressant and anti-cancer activities. The furan ring is disordered over two orientations [site occupancies 0.690 (12)/0.310 (12)] related by a rotation of 180°. The ring conformations are chair for the cyclo-hexane ring, boat for the cyclo-hexa-diene ring and twist for the pyrimidine ring. The crystal packing is determined solely by van der...

In the title compound, [ReCl(C16H18N4)(CO)3], the Re(I) ion is coordinated in a distorted octa-hedral geometry by one Cl atom, two N atoms of the bidentate ligand and three carbonyl groups. The cyclo-hexane group is orientated in a transoid fashion with respect to the chloride ligand. In the crystal, N-H⋯Cl hydrogen bonds link complex mol-ecules, forming a two-dimensional network parallel to (1...

In the title compound, C(18)H(22)O, the dihedral angle between the carbonyl and benzene planes is 69.11 (6)°. In the adamantyl group, the three fused cyclo-hexane rings have almost ideal chair conformations, with C-C-C angles in the range 108.14 (11)-110.50 (11)°. No specific inter-molecular inter-actions (other than van der Waals inter-actions) are present in the crystal.
