title: Bis[μ-1,2-bis-(1H-imidazol-1-ylmethyl)benzene-κN:N]disilver(I) bis-(4-amino-2,5-dichloro-benzene-sulfonate) tetra-hydrate.
abstract: 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-dichloro-benzene-sulfonate anions and four water mol-ecules. Each centrosymmetric dicationic unit has a dinuclear structure in which two Ag(I) atoms are bridged by two 1,2-bis-(1H-imidazol-1-yl-meth-yl)benzene ligands in a slightly distorted linear coordination geometry. The 4-amino-2,5-dichloro-benzene-sulfonate anion does not coordinate with the Ag(I) center, acting only as a counteranion. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds form a three-dimensional network.
