Abstract
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.
