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-thiosaccharinate one-dimensional coordination polymer {systematic name: catena-poly[[[aquatetrakis(μ-1,1-dioxo-1,2-benzisothiazole-3-thiolato-κN:S:S)tetrasilver(I)]-μ-4,4'-(propane-1,3-diyl)dipyridine-κN:N'] dimethyl sulfoxide hemisolvate]}, {[Ag(CHNOS)(CHN)(HO)]·0.5CHOS}, 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.
在配位聚合物的潜在应用中，电导率在技术应用方面备受关注。我们报道了一种银-硫代糖精一维配位聚合物的合成、晶体结构和光谱分析{系统名称：链状聚[[[水合四（μ-1,1-二氧代-1,2-苯并异噻唑-3-硫醇根-κN:S:S）四银（I）]-μ-4,4'-（丙烷-1,3-二基）二吡啶-κN:N']二甲基亚砜半溶剂化物]}，{[Ag(CHNOS)(CHN)(HO)]·0.5CHOS}，其中4,4'-（丙烷-1,3-二基）二吡啶配体作为间隔基。该结构的一个相关特征是存在异常短的Ag...Ag距离，为2.80.8306 (9) Å，处于亲银相互作用范围内，通过对低频光谱的拉曼研究在实验上得到证实，并通过对计算电子密度的分子中的原子（AIM）分析在理论上得到佐证。电导率测量表明，这种配合物可以作为具有中等电导率的半导体。
