Bis[μ-1,2-bis­(1H-imidazol-1-ylmethyl)benzene-κ(2) N (3):N (3′)]disilver(I) bis­(4-amino-2,5-dichloro­benzene­sulfonate) tetra­hydrate

The asymmetric unit of the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(6)H(4)Cl(2)NO(3)S)(2)·4H(2)O, 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—H⋯O and N—H⋯O hydrogen bonds form a three-dimensional network.
