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.
