Dibenzo-18-crown-6
The asymmetric unit of the title compound, C(20)H(24)O(6), contains two mol-ecules that are identical within standard deviations concerning bond lengths and angles as well as their conformations. In the crystal structure, weak C-H⋯O inter-actions help to consolidate the packing.

The ternary complexes 18C6-4H20 -2 H N ( S 0 2Ph)2 (3) and 18C 6-2H 20 2 H N ( S 0 2C6H44 F ) 2 (4) were obtained by co-crystallization of 18-crown-6 (18C6) with the appropriate di(arenesulfonyl)amine from aqueous solutions and characterized by low-temperature X-ray diffraction. The crystal structures consist of monomeric formula units displaying crystallographic C, symmetry for 3 (monoclinic, ...

From extraction experiments and γ-activity measurements, the extraction constant corresponding to the equilibrium Na+(aq) + A-(aq) + 1(nb) left arrow over right arrow 1•Na+(nb) + A-(nb) taking place in the two-phase water-nitrobenzene system (A- = picrate, 1 = dibenzo-18-crown-6; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as was log Kex (1•Na+, A-) = 1.7 ± 0.1. Further, the stab...
متن کامل(18-Crown-6)(trifluoromethanesulfonato)sodium
The title compound, [Na(CF(3)O(3)S)(C(12)H(24)O(6))], features a sodium cation that is coordinated by eight O atoms in an irregular hexa-gonal bipyramidal environment. The equatorial positions are occupied by the six O atoms of an 18-crown-6 ether ring. In the axial positions, there is one O atom of a trifluoro-methane-sulfonate anion and an ether O atom of a symmetry-equivalent crown ether rin...
