In the title compound, 2CH6N3+·2Br−·C12H24O6, the 18-crown-6 molecule 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 molecules via N—H⋯O and N—H⋯Br hydrogen bonds, thus forming a three-dimensional network.
