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...
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 ...
متن کامل2-Methoxyethanaminium periodate 18-crown-6 clathrate
In the crystal structure of the title organic salt, C(3)H(10)NO(+)·IO(4) (-)·C(12)H(24)O(6), the protonated 2-meth-oxy-ethanaminium (CH(3)OC(2)H(4)-NH(3) (+)) cation forms a 1:1 supra-molecular rotator-stator complex with the 18-crown-6 mol-ecule via N-H⋯O hydrogen bonds. The (CH(3)OC(2)H(4)-NH(3) (+)) group is attached from the convex side of the bowl-shaped crown, in contrast to similar ammon...
