Bis{2,2'-[(2-amino-eth-yl)aza-nedi-yl]diethanaminium} di-μ-sulfido-bis-(disulfido-germanate).

In the title compound, (C(6)H(20)N(4))(2)[Ge(2)S(6)], the dimeric [Ge(2)S(6)](4-) anion is formed by two edge-sharing GeS(4) tetra-hedral 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.
