Bis[μ-1,2-bis(1H-imidazol-1-ylmethyl)benzene-κ2N3:N3′]disilver(I) bis(4-amino-2,5-dichlorobenzenesulfonate) tetrahydrate

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 AgI 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 AgI 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.
