Abstract: The asymmetric unit of the title compound, [Ag₂(C₁₄H₁₄N₄)₂](C₆H₄Cl₂NO₃S)₂·4H₂O, contains one-half of each of two independent dicationic units, two 4-amino-2,5-dichlorobenzenesulfonate anions and four water molecules. Each centrosymmetric dicationic unit has a dinuclear structure in which two Ag^I atoms are bridged by two 1,2-bis(1H-imidazol-1-ylmethyl)benzene ligands in a slightly distorted linear coordination geometry. The 4-amino-2,5-dichlorobenzenesulfonate anion does not coordinate with the Ag^I center, acting only as a counteranion. In the crystal structure, intermolecular O-HO and N-HO hydrogen bonds form a three-dimensional network.
