[Show abstract][Hide abstract] ABSTRACT: In the title compound, [Ag2(C14H14N4)2](C7H4O6S)·CH3OH·3H2O, the complex dication has a binuclear structure in which each AgI ion is two-coordinated in a slightly distorted linear coordination geometry. The two AgI atoms are bridged by two 1,2-bis[(1H-imidazol-1-yl)methyl]benzene (IBI) ligands, forming a 22-membered ring. In the dication, π–π interactions 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 molecules, anions and methanol solvent molecules are linked into chains along the b axis by O—H...O hydrogen bonds. In addition, π–π interactions 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).
[Show abstract][Hide abstract] 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.
