Double Pseudo-Polymeric Gold(III)-Mercury(II) Complexes [Au(S2CNR2)2]nX [R2 = (CH2)6, (CH2)4O] Containing ([HgCl3]−)n, [HgCl4]2− and [Hg2Cl6]2− Anions: Chemisorption Synthesis, Principles of Supramolecular Self-Assembly, and Thermal Behavior

Abstract

Novel pseudo-polymeric complexes of gold(III)-mercury(II) with cyclic alkylene dithiocarbamate ligands: ([Au{S2CN(CH2)6}2][HgCl3])n, ([Au{S2CN(CH2)6}2]2[HgCl4]·H2O)n, and ([Au{S2CN(CH2)4O}2]2[Hg2Cl6])n have been obtained and structurally characterized. The sophisticated supramolecular structure of the obtained compounds is realized due to secondary non-valent Au⋯S interactions and includes mononuclear and binuclear cations and anions as structural units as well as cationic and anionic polymer chains. The thermal behavior of the obtained complexes has been studied by means of simultaneous thermal analysis. The products of thermal transformations of the complexes are reduced elemental gold and HgCl2.
