Reactivity of Silver(I) Diethyldithiocarbamate and Ion-Polymeric Complexes {[Au(S2CNEt2)2][AgCl2]}n and {[Au(S2CNEt2)2]2[AgCl2]Cl·2H2O}n: Synthesis, Supramolecular Structures, and Thermal Behavior

Аннотация

New ion polymeric gold(III)–silver(I) complexes, {[Au(S₂CNEt₂)₂][AgCl₂]}_n and {[Au(S₂CNEt₂)₂]₂[AgCl₂]Cl·2H₂O}_n have been synthesized and characterized by X-ray diffraction data and IR spectra. The structure of the first complex is represented by [Au{S₂CNEt₂}₂]⁺ complex cations and polymeric silver chloride anion ([AgCl₂]^–)_n; the second complex consists of isomeric cations, linear [AgCl₂]^– anions, chloride ions, and water molecules. Gold cations are involved in zigzag (AuAuAu angle 99.06°) and linear polymeric chains via secondary Au···S bond pairs. Thermal decomposition of the complexes with regeneration of gold and silver has been studied by simultaneous thermal analysis (STA).
