Three trinuclear cationic silver nanoclusters based-on bis-(phosphine) ligands and stabilized by CF₃SO₃⁻ anions, displayed excellent photocurrent responses and electrochemical properties.

Structure and electrical properties of a one-dimensional polymeric silver thiosaccharinate complex with argentophilic interactions

Among the potential applications of coordination polymers, electrical conductivity ranks high in technological interest. We report the synthesis, crystal structure and spectroscopic analysis of an Ag^I-thiosaccharinate one-dimensional coordination polymer {systematic name: catena-poly[[[aquatetrakis(μ₃-1,1-dioxo-1,2-benzisothiazole-3-thiolato-κ³N:S³:S³)tetrasilver(I)]-μ₂-4,4'-(propane-1,3-diyl)dipyridine-κ²N:N'] dimethyl sulfoxide hemisolvate]}, {[Ag₄(C₇H₄NO₂S₂)₄(C₁₃H₁₄N₂)(H₂O)]·0.5C₂H₆OS}_n, with the 4,4'-(propane-1,3-diyl)dipyridine ligand acting as a spacer. A relevant feature of the structure is the presence of an unusually short Ag...Ag distance of 2.8306 (9) Å, well within the range of argentophilic interactions, confirmed experimentally as such by a Raman study on the low-frequency spectrum, and corroborated theoretically by an Atoms in Molecules (AIM) analysis of the calculated electron density. Electrical conductivity measurements show that this complex can act as a semiconductor with moderate conductivity.
