Two silver(I) complexes of 4,5-ethylenedithio-1,3-dithiole-2-thione (C₅H₄S₅), {[Ag(C₅H₄S₅)₃]ClO₄·CH₃CN}₂ and [Ag(C₅H₄S₅)CF₃SO₃] have been synthesized and characterized crystallographically. They are unique dimer and two-dimensional structures respectively and assembled by S···S contacts (Figure 1). The finding of the shortest S···S contacts (3.284 Å, 3.262 Å) in these complexes indicates that the coordination linkage in metal complexes of organic donor can be expected to control the intra- or inter-molecular interactions. The coordination mode of the C₅H₄S₅ ligand has also been systematically discussed.
