In　the　title　compound,　[Cu(C2H8N2)2](C14H6O8S2),　the　CuII　atom　lies　on　an　inversion　centre　and　is　coordinated　by　two　ethyl-enediamine　ligands　in　a　square-planar　geometry.　9,10-Dioxoanthracene-2,6-disulfonate　anions,　also　lying　on　inversion　centres,　coordinate　weakly　to　CuII　and　accept　N　-　H⋯O　hydrogen　bonds　from　ethyl-enediamine,　linking　the　[Cu(C2H8N2)2]　2+　cations　into　chains.　Adjacent　chains　are　linked　into　extended　two-dimensional　networks　via　N　-　H⋯O　hydrogen　bonds.　©　International　Union　of　Crystallography　2007.
