نویسنده
چکیده
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.

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.
