The title compound, (C8H13N2)4.[Sb6I22].4H2O, crystallizes with an Sb6I224- anion consisting of edge-shared distorted octahedra [Sb-Irange = 2.789 (2)-3.421 (2) Å] and monoprotonated tetramethylpyrazinium cations which are bridged by water solvent molecules to form infinite chains [N...O = 2.69 (1)-2.95 (1) Å]. The anion has a structure corresponding to a section from a layer of the CdI2 structure, similar to that previously observed when crystallized with a bis(cyclopentadiene)iron(III) cation [Pohl, Lotz, Saak & Haase (1989). Angew. Chem. Int. Ed. Engl. 28, 344-345].
