新的导电配位聚合物的一种很有前途的策略是将d10金属离子与二硫杂环戊烯连接物相结合,d10金属离子可以容忍较短的金属···金属距离,二硫杂环戊烯以其“非无害”的氧化还原行为而闻名。本研究探讨了2,3-吡嗪二硫醇(H_2pdt)对铜、银离子的配位化学,突出了它们的异同。这种合成方法从完全质子化的配体开始,可以分离出具有形式CuI原子的同质双(二硫杂环戊烯)络合物[Cu(H_2pdt)_2]Cl(1)。该配合物进一步转变为金属···金属间距较短的一维配位聚合物,一维[Cu(Hpdt)](2Cu)。较大的Ag+离子直接形成了非常相似的配位聚合物一维[Ag(Hpdt)](2AG),没有任何中间金属络合物的出现。配位聚合物1D[Cu(H_2pdt)I](4)和络合物1一样,以二硫酮形式具有完全质子化的H_2pdt配体。加热后,两个化合物都发生了自氧化和配体的脱氢反应,分别形成了开壳中性铜(II)络合物[Cu(Hpdt)2](3)和配位聚合物1D[Cu2I2(Hpdt)(Hpdt)](5)。对所有化合物的晶体结构进行了深入的讨论。此外,通过UV-Vis-NIR光谱、循环伏安、变温磁化率和直流电导率测量,研究了1,3和三个一维配位聚合物2AG、2Cu和4的性质。借助DFT模拟,对实验结果进行了比较和讨论。
A promising strategy for new electrically conductive coordination polymers is the combination of d10metal ions, which tolerate short metal···metal distances, with dithiolene linkers, known for their “non-innocent” redox behavior. This study explores the coordination chemistry of 2,3-pyrazinedithiol (H2pdt) toward Cu+and Ag+ions, highlighting similarities and differences. The synthetic approach, starting with the fully protonated ligand, allowed the isolation of a homoleptic bis(dithiolene) complex with formal CuIatoms, [Cu(H2pdt)2]Cl (1). This complex was further transformed to a 1D coordination polymer with short metal···metal distances,1D[Cu(Hpdt)] (2Cu). The larger Ag+ion directly built up a very similar coordination polymer,1D[Ag(Hpdt)] (2Ag), without any appearance of an intermediate metal complex. The coordination polymer1D[Cu(H2pdt)I] (4), like complex1, bears fully protonated H2pdt ligands in their dithione form. Upon heating, both compounds underwent auto-oxidation coupled with a dehydrogenation of the ligand to form the open-shell neutral copper(II) complex [Cu(Hpdt)2] (3) and the coordination polymer1D[Cu2I2(H2pdt)(Hpdt)] (5), respectively. For all presented compounds, crystal structures are discussed in-depth. Furthermore, properties of1,3, and those of the three 1D coordination polymers,2Ag,2Cu, and4, were investigated by UV–vis–NIR spectroscopy, cyclic voltammetry, and variable-temperature magnetic susceptibility, and direct current (dc)-conductivity measurements. The experimental results are compared and discussed with the aid of DFT simulations.
