Ethane-1,2-diaminium 4,4'-sulfonyl-dibenzoate.
In the title salt, C(2)H(10)N(2) (2+)·C(14)H(8)O(6)S(2-), both the ethyl-ene-diaminium cations and the 4,4'-sulfonyl-dibenzoate dianions have crystallographic twofold rotational symmetry. They are inter-linked by aminium N-H⋯O(carboxyl-ate) hydrogen-bonding associations, giving sheets parallel to (101) and are further linked along [010], forming a three-dimensional structure.
