In the crystal of the title compound, 2CH6N3+·C10H6O6S22−·C12H24O6, the 1,5-naphthnalenedisulfonate anion and the 18-crown-6 molecule lie across inversion centers. The guanidinium cation links with the 1,5-naphthnalenedisulfonate anion and 18-crown-6 molecule via N—H⋯O hydrogen bonds.
For applications of crown ethers, see: Clark et al. (1998 ▶). The title compound was obtained during a search for new hydrogen-bonding-type dielectric materials. For ferroelectric metal-organic 18-crown-6 clathrates, see: Fu et al. (2009 ▶, 2011 ▶); Ye et al. (2006 ▶); Zhang et al. (2008 ▶, 2010 ▶).
