The structure of the title salt, (C(6)H(14)N)(2)[CuBr(4)], is built up from cyclo-hexyl-ammonium cations and tetra-bromidocuprate anions, the latter being located on an inversion center. In the crystal, anions and cations are inter-connected by N-H⋯Br hydrogen bonds, forming ribbons parallel to [0-11].

In the title salt, C6H14N(+)·NO3 (-), the cyclo-hexyl ring adopts a chair conformation. The ammonium group occupies an equatorial position and the crystal struture is stabilized by inter-molecular N-H⋯O hydrogen-bonding inter-actions, resulting in a three-dimensional network.

The title compound, C(22)H(36)NO(2)P, features a P atom bonded to a phenyl ring, a cyclo-hexyl-amine unit and the O atom of a menthyl group. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds connect mol-ecules into a one-dimensional chain in the b direction.

In the title compound, C(20)H(25)NO(2)S, the cyclo-hexyl ring exists in a chair form and the mean plane through all six atoms makes dihedral angles of 56.12 (9) and 55.19 (10)° with the benzene and phenyl rings, respectively. The dihedral angle between the two aromatic rings is 77.23 (7)°. A weak intra-molecular C-H⋯O interaction occurs.

In the crystal structure of the title compound, C(39)H(54)BCl(2)P, the phospho-rus atom is coordinated by a dichloro-phenyl-borane unit. The substituted biphenyl group and the two cyclo-hexyl groups at the phospho-rus atom are arranged in such a way to avoid steric crowding in the mol-ecule as far as possible.

In the crystal structure of the title compound, C(18)H(23)NO(2), there are only van der Waals inter-actions present. The cyclo-hexyl ring has a chair conformation. The longer axes of the displacement parameters of the non-H atoms forming the ethyl-methyl-carboxyl-ate skeleton are perpendicular to the plane through the non-H atoms of this skeleton.

The title compound, C(21)H(24)Br(2)N(2)O(3), was synthesized by the condensation reaction of 3-methoxy-salicylaldehyde with 4-(2-amino-3,5-dibromo-benzyl-amino)cyclo-hexa-nol in a methanol solution. The dihedral angle between the two benzene rings is 76.4 (3)°. The cyclo-hexyl ring adopts a chair configuration. There is an intra-molecular O-H⋯N hydrogen bond which affects the solid state confor...

The title compound, C(28)H(30)N(2), is a symmetrical 2:2 product from the condensation of indole and cyclo-hexa-none. It is the only reported 5,11-dihydro-indolo[3,2-b]carbazole compound in which the spiro atoms are quaternary C atoms. Crystals were grown by vapor diffusion in a three-zone electric furnace. The mol-ecule resides on a crystallographic inversion center. The cyclo-hexyl rings are ...

The preparation of the title compound, C26H25N, was achieved by the condensation of an ethano-lic mixture of benzaldehyde, cyclo-hexa-none and ammonium acetate in a 2:1:1 molar ratio. There are two crystallographically independent mol-ecules in the asymmetric unit. The two cyclo-hexyl rings adopt an anti-envelope conformation with the benzyl moiety adopting a cis conformation with respect to th...

The title compound, C(17)H(17)ClN(2)O(3)·0.5C(6)H(12), was prepared by the condensation reaction of 4-meth-oxy-3-(propanamido)-benzoic acid with 4-chloro-aniline. The Cl atom, the propionyl CH(3) group and the cyclo-hexyl CH(2) group are disordered over two sets of sites of equal occupancy in both mol-ecules. The cyclo-hexane solvent mol-ecule is disordered over two orientations which were mode...
