In the title compound, C21H21FO2S, the cyclo-hexyl ring adopts a chair conformation. The 2-fluoro-phenyl ring makes a dihedral angle of 88.47 (4)° with the mean plane [r.m.s. deviation = 0.013 (1) Å] of the benzo-furan fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions, forming chains propagating along [100]. The crystal structure also exhibits slipped π-π int...

The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with the O atoms in equatorial cis positions. In ...

In the title compound, C(9)H(13)NOS(2), the complete mol-ecule is generated by crystallographic mirror symmetry, with all the non-H atoms of the rhodanine (2-thioxo-1,3-thia-zolidin-4-one) system and two C atoms of the cyclo-hexyl ring lying on the reflecting plane. The conformation is stabilized by intra-molecular C-H⋯O and C-H⋯S inter-actions. In the crystal, weak π-π inter-actions at a dista...

In the title compound, [Sn(C(6)H(11))(2)(C(13)H(15)NO(4))], the Sn atom is five-coordinate and adopts a distorted trigonal-bipyramidal SnNC(2)O(2) geometry with the O atoms in axial positions. The metal atom forms five- and six-membered chelate rings with the O,N,O'-tridentate ligand. The two cyclo-hexyl groups bound to the Sn atom adopt chair conformations, with the Sn-C bonds in equatorial po...

In the title compound, [Pt(C(30)H(31)NP(2))(2)](PF(6))(2)·2CH(2)Cl(2), the four-coordinated Pt(II) atom, situated on an inversion centre, exhibits a highly distorted square-planar geometry illustrated by the P-Pt-P bite angle of 70.76 (3)°. The cyclo-hexyl ring and one of the phenyl rings display 0.630 (7):0.37 (7) and 0.60 (2):0.40 (2) positional disorder, respectively. The dichloro-methane so...

In the title compound, C21H21FO2S, the cyclo-hexyl ring adopts a chair conformation. The 2-fluoro-benzene ring makes a dihedral angle of 38.68 (6)° with the mean plane [r.m.s. deviation = 0.018 (2) Å] of the benzo-furan fragment. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds into dimers, which are further packed into stacks along the c axis by C-H⋯O hydrogen bonds. In a...

In the title compound, C22H23FO2S, the cyclo-hexyl ring adopts a chair conformation. The dihedral angle between the mean plane [r.m.s. deviation = 0.013 (2) Å] of the benzo-furan ring system and the mean plane [r.m.s. deviation = 0.009 (2) Å] of the 3-fluoro-phenyl ring is 24.80 (4)°. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds, forming chains along [10-1]. These chains are...

The asymmetric unit of the title compound, C(13)H(18)N(2)O(3)S, contains two mol-ecules with similar conformations. In both mol-ecules, the cyclo-hexyl rings adopt chair conformations, with the attached N atom in an equatorial orientation and an intra-molecular N-H⋯O hydrogen bond generates an S(7) ring. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules and a C-H⋯O hydrogen bond is also ...

The title compound, C(20)H(24)O(4), was synthesized from the reaction of 2-oxo-2H-chromene-3-acyl chloride and menthol. The mean plane of the ester group and that of the four essentially planar (maximum deviation 0.0112 Å) C atoms of the chair-form cyclo-hexyl ring form dihedral angles of 43.8 (3) ° and 81.8 (1)°, respectively, with the mean plane of the coumarin ring system. In the crystal str...

The title compound, C(24)H(25)Br, packs efficiently in the crystal structure with no solvent-accessible voids and several inter-molecular H⋯H contacts approximating the sum of the van der Waals radii. The mol-ecule is quite crowded, with intra-molecular Br⋯H and C⋯H contacts ca 0.38 and 0.30 Å, respectively, less than the sum of the corresponding van der Waals radii. All cyclo-hexyl rings adopt...
