Guanidinium bromide–18-crown-6 (2/1)
In the title compound, 2CH(6)N(3) (+)·2Br(-)·C(12)H(24)O(6), the 18-crown-6 mol-ecule lies about an inversion center, whereas the guanidinium cation and bromide anion are in general positions. The guanidinium cations link with the bromide anions and the crown ether mol-ecules via N-H⋯O and N-H⋯Br hydrogen bonds, thus forming a three-dimensional network.

In the crystal of the title compound, 2CH(6)N(3) (+)·C(10)H(6)O(6)S(2) (2-)·C(12)H(24)O(6), the 1,5-naphthnalenedisulfonate anion and the 18-crown-6 mol-ecule lie across inversion centers. The guanidin-ium cation links with the 1,5-naphthnalenedisulfonate anion and 18-crown-6 mol-ecule via N-H⋯O hydrogen bonds.
متن کاملDibenzo-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...
