The title salt, (C6H14N2)2[Sb2Cl10]·2H2O, was obtained by slow evaporation of an acidic solution of 1,4-di­aza­bicyclo­[2.2.2]octane and SbCl3. The crystal structure consists of (C6H14N2)2+ cations, [Sb2Cl10]4− double octa­hedra and lattice water mol­ecules. All mol­ecular components are situated on special positions. The cation and the lattice water mol­ecule exhibit mirror symmetry, whereas the anion has site symmetry 2/m. The cations, anions and water mol­ecules are alternately arranged into columns along [010]. Individual columns are joined into layers extending along (001). Intra­layer N—H⋯O and inter­layer N—H⋯Cl hydrogen-bonding inter­actions lead to the formation of a three-dimensional network.

In a novel one-dimensional hybrid compound, the inorganic part contains zigzag chains formed by corner-sharing [SbCl6]3− octa­hedra. 1,4-Diazo­niabi­cyclo­[2.2.2]octane dications cations are lodged around the anionic framework. Water mol­ecules play an important role in the structure connectivity.
