Synthesis and X-ray crystal structures of dinuclear silver(I) complexes of heteroaryl thioethers

The X-ray crystal structures of four complexes, obtained by reaction of silver nitrate with four different heteroaryl thioethers, are described. In these compounds the ligands act as dinuclear bridges between silver atoms, with coordination exclusively through the nitrogen donor atoms. All ligands form dinuclear complexes, either as discrete species or as higher aggregates involving additional nitrate bridges. π–π Stacking interactions provide extra stabilisation in some of the structures.
