Resumen:
Among the pot ential ap plications of coord inatio n pol ymers, elect rical conductivity ran ks high in techn ological interest. We rep ort the synthesis, crystalstructure and spectro scopic analysis of an AgI?thiosaccharinate one-dimensional coordination polymer {systematic name: catena-poly[[[aquatetrakis(3-1,1-dioxo-1,2-benzisothiazole-3-thiolato-3N:S3:S3)tetrasilver(I)]-2-4,4 0-(propane-1,3-diyl)dipyridine-2N:N0] dimethyl sulfoxide hemisolvate]}, {[Ag4(C7H4NO2S2)4-(C13H14N2)(H2O)] 0.5C2H6OS}n, with the 4,4 0-(propane-1,3-diyl)dipyridineligand acting as a spacer. A relevant feature of the structure is the presence of anunusually short Ag Ag distance of 2.8306 (9) A˚ , well within the range ofargentophilic interactions, confirmed experimentally as such by a Raman studyon the low-frequency spectrum, and corroborated theoretically by an Atoms inMolecules (AIM) analysis of the calculated electron density. Electricalconductivity measurements show that this complex can act as a semiconductorwith moderate conductivity.
