摘要

利用溶液(1H、13C{1H})核磁共振和傅立叶变换红外光谱,获得了[Au{S2CN(C4H9)2}2][AgCl2] (1)和[Au{S2CN(CH2)6}2]3[AgCl2][Ag0.59Au0.41Cl2]2的伪聚合双复合物,并对其进行了化学鉴定。根据 XRD 分析,上述两种晶体化合物都形成了复杂的超分子结构。这些超分子结构的自组装和结构稳定是通过许多次级相互作用实现的:Ag⋯S、Cl⋯S(在 1、2 中)和 Au⋯Cl、Au⋯S(在 2 中),它们在复合物的离子结构单元之间产生。这些离子间二级相互作用的综合表现导致了 (⋯[Au(S2CNBu2)2]⋯[AgCl2]⋯)n (1) 和 (⋯[Au2(S2CNHm)4]⋯[AgCl2]⋯)n (2) 两种假聚合物链的形成。为了研究制备的化合物的热性能,我们使用了同步热分析(STA)技术,从而确定了定量回收结合金属的条件。此外,实验还揭示了所制备的金(III)-银(I)化合物对非致病性烟曲霉菌株具有很高的体外生物活性。

Double pseudo-polymeric complexes of [Au(S2CNBu2)2][AgCl2] and [Au(S2CNHm)2]3[AgCl2][Ag0.59Au0.41Cl2]2: Preparation, supramolecular self-assembly, thermal behaviour and anti-mycobacterial activity

Double pseudo-polymeric complexes of [Au(S2CNBu2)2][AgCl2] and [Au(S2CNHm)2]3[AgCl2][Ag0.59Au0.41Cl2]2: Preparation, supramolecular self-assembly, thermal behaviour and anti-mycobacterial activity

Pseudo-polymeric double complexes of [Au{S2CN(C4H9)2}2][AgCl2] (1) and [Au{S2CN(CH2)6}2]3[AgCl2][Ag0.59Au0.41Cl2]2 have been obtained and chemically identified using solution (1H, 13C{1H}) NMR and FT-IR spectroscopy. According to XRD analysis, it was established that both of the above crystalline compounds form complicated supramolecular architectures. Self-assembly and structural stabilization of these supramolecular formations are achieved due to numerous secondary interactions: Ag⋯S, Cl⋯S (in 1, 2) and Au⋯Cl, Au⋯S (in 2), which arose between the ionic structural units of the complexes. The combined manifestation of these interionic secondary interactions leads to the construction of two types of pseudo-polymeric chains of (⋯[Au(S2CNBu2)2]⋯[AgCl2]⋯)n (1) and (⋯[Au2(S2CNHm)4]⋯ [AgCl2]⋯)n (2). To study the thermal behaviour of the prepared compounds, the simultaneous thermal analysis (STA) technique was used, which allowed us to determine the conditions for the quantitative recovery of bound metals. Moreover, a high in vitro biological activity for each of the prepared gold(III)-silver(I) compounds against the non-pathogenic strain Mycolicibacterium smegmatis was experimentally revealed.

期刊介绍: Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
