Abstract
For freshly precipitated zinc complex with cyclic morpholinedithiocarbamate (MfDtc) ligand, the ability to extract gold(III) from solutions in 2 M HCl was studied. The hydrated ionic type polymeric complexes, ([Au{S2CN(CH2)4O}2]2[ZnCl4] · 2H2O) n (I) and ([Au{S2CN(CH2)4O}2]Cl · 2H2O) n (II), were preparatively isolated as individual gold-binding forms. The molecular and supramolecular structures of compounds I and II were established from single-crystal X-ray diffraction data; the thermal behavior was studied by simultaneous thermal analysis (STA). The structures of both compounds contain polymeric chains formed by the complex cations [Au{S2CN(CH2)4O}2]+ through secondary non-valence Au⋯S bonds. The anionic part of the complexes is presented by structurally disordered tetrahedral [ZnCl4]2− ions (in I) and polymeric chains involving water molecules and Cl− anions (in II). The multistage thermal decomposition process comprises dehydration of the complexes, thermolysis of the cationic and anionic moieties with gold(III) reduction to the metal, release of zinc chloride, and partial formation of ZnS.
