title: Bis[μ-1,2-bis-(1H-imidazol-1-ylmeth-yl)benzene-κN:N]disilver(I) 3-carboxyl-ato-4-hydroxy-benzene-sulfonate methanol solvate trihydrate.
abstract: In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(7)H(4)O(6)S)·CH(3)OH·3H(2)O, the complex dication has a binuclear structure in which each Ag(I) ion is two-coordinated in a slightly distorted linear coordination geometry. The two Ag(I) atoms are bridged by two 1,2-bis-[(1H-imidazol-1-yl)meth-yl]benzene (IBI) ligands, forming a 22-membered ring. In the dication, π-π inter-actions are observed between the imidazole rings with centroid-centroid distances of 3.472 (3) and 3.636 (3) Å. In the crystal, the uncoordinated water mol-ecules, anions and methanol solvent mol-ecules are linked into chains along the b axis by O-H⋯O hydrogen bonds. In addition, π-π inter-actions are observed between the benzene rings of the IBI ligands, with a centroid-centroid distance of 3.776 (2) Å. The sulfonate group is disordered over two orientations with occupancies of 0.676 (12) and 0.324 (12).
