In the title compound, (C6H20N4)2[Ge2S6], the dimeric [Ge2S6]4− anion is formed by two edge-sharing GeS4 tetra­hedral units. The average terminal and bridging Ge—S bond lengths are 2.158 (14) and 2.276 (6) Å, respectively. The anions and the diprotonated ammonium cations are organized into a three-dimensional network by N—H⋯S and N—H⋯N hydrogen bonds.
