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.
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...

In the title compound, [CuBr(2)(H(2)O)(2)]·C(12)H(24)O(6)·2H(2)O, the Cu(II) atom, which is situated on an inversion centre and has a slightly distorted square-planar geometry, and the two coordinated water mol-ecules are linked to the 18-crown-6 macrocycles by O-H⋯O hydrogen bonds. The water mol-ecule of crystallization further links the metal complex and the crown ether macrocycles into a cha...
متن کاملSolvent Effect on Stability and Thermodynamic Behavior of Complex of 18-Crown-6 with Hydroxyl Ammonium Cation
The complexation reaction between hydroxyl ammonium (HONH3+ ) cation with 18-crown-6 (18C6) ligand was studied in dimethylsulfoxide – water (DMSO-H2O), methanol – water (MeOH-H2O) and dimethylformamid – methanol (DMF-MeOH), binary solutions at different temperatures using conductometric method. The obtained results show that the stoichiometry of t...

In the title compound, C(6)H(7)ClN(+)·BF(4) (-)·C(12)H(24)O(6), the complete cation is generated by crystallographic mirror symmetry, with two C atoms and the N and Cl atoms lying on the mirror plane. The complete crown ether is also generated by mirror symmetry, as is the anion (in which the B and two F atoms lie on the mirror plane). The -NH(3) (+) group of the cation inserts into the crown-e...
