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 کاملComplexation of Hydronium Ion with Several Crown Ethers in Nitromethane Solution
The interaction between hydronium ion and several crown ethers was studied via conductometry in nitromethane at 25 °C and 1H-NMR techniques. The stabilities of the resulting 1:1 complexes were determined from the conductance data and found to vary in the order DC18C6 > 18C6 > DB30C10 > DB24C8 > DB18C6 > ~B15C5 > DB21C7. For the first time, evidences for the formation of a 2:1 san...
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...
متن کاملMethylammonium tetrafluoridoborate 18-crown-6 clathrate
In the title compound, CH(3)NH(3) (+)·BF(4) (-)·C(12)H(24)O(6), the methyl-ammonium cation makes three N-H⋯O hydrogen bonds to the 18-crown-6 mol-ecule. The -NH(3) (+) and -CH(3) groups of the cation adopt a staggered conformation. The F atoms of the tetra-fluoridoborate anion are disordered over two sets of sites in a 0.519 (11):0.481 (11) ratio. Weak C-H⋯F inter-actions occur in the crystal, ...
متن کامل4-Methylanilinium tetrafluoroborate 18-crown-6 clathrate
In the title compound, C(7)H(10)N(+)·BF(4) (-)·C(12)H(24)O(6), the proton-ated 4-methyl-anilinium cation inter-acts with 18-crown-6 forming a rotator-stator structure, (C(6)H(4)CH(3)NH(3) (+))(18-crown-6), through three bifurcated N-H⋯(O,O) hydrogen bonds between the ammonium groups of the cations (-NH(3)) and the O atoms of the crown ether mol-ecule. The BF(4) (-) anions, the methyl group and ...
