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 AgI–thiosaccharinate one-dimensional coordination polymer {systematic name: catena-poly[[[aquatetrakis(μ3-1,1-dioxo-1,2-benzisothiazole-3-thiolato-κ3 N:S 3:S 3)tetrasilver(I)]-μ2-4,4′-(propane-1,3-diyl)dipyridine-κ2 N: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.

The conductivity of aqueous and non-aqueous liquid electrolyte solutions was determined in a low frequency region where no dispersion due to dielectric relaxation of the solvent-solute system can be found. The values of the equivalent conductance of concentrated alkali chloride and nitrate solutions were obtained by measurements in a special cell with high cell constant

AbstractAlthough quantitative interpretation of the low-frequency electrical conductivity of ice cores from central Greenland is complicated by temperature variations of the measured core, annual layers can be recognized in sections of the core that are not impacted by non-seasonal features. Ambiguities in counting of annual layers can be minimized by comparing the electrical conductivity measurements to measurements of dust concentration and visual stratigraphy. A non-linear relationship between applied voltage and the current measured across two electrodes complicates the quantitative comparison of measurements made with different equipment, but does not affect the overall shape of the observed features.
