Crystalline silver(I) coordination compounds [Ag2(HL)4(C6H5SO3)2]·0.5C3H7OH (1) and [Ag2(HL)(L)(CH3C6H4SO3)] (2) (HL = 3-(prop-2-en-1-yl)-2-thioxoimidazolidin-4-one) have been obtained using silver(I) salts and the organic ligand HL. Three independent Ag(I) atoms in crystal 1 adopt exclusively different coordination environment: tetragonal pyramidal, seesaw and distorted tetrahedral. In crystal 2 metal ions coordination polyhedra are characterized by seesaw and distorted tetrahedral arrangements. Thiohydantoin molecules in both structures are attached to Ag(I) only through thiohydantoin S-atom, while its anionic form in 2 plays a role of N,S-linker. C6H5SO3− anions in 1 are bound to the Ag(I) ions in a bridging mode, connecting silver ions into serpentine-like {Ag4(C6H5SO3)4}n chains, within which silver ions are additionally bind with µ2-S atoms of HL. Simultaneous coordination of HL and L− moieties in polymeric chains of 2 allow the formation of Ag….Ag metallophilic interactions with the distance range of 2.99–3.13 Å. |
