N2 - Abstract: The chemisorption binding of gold(III) by freshly precipitated binuclear zinc dithiocarbamates [Zn2(S2CNR2)4] from solutions in 2 M HCl makes it possible to obtain heteroligand complexes [Au(S2CNR2)Cl2]: R = CH3 (I), iso-C3H7 (II); R2 = (CH2)6 (III). The structural organization of complexes I, II, and III is determined by X-ray diffraction analysis (CIF files CCDC no. 1813107, 1813369, and 1813108, respectively). The distorted square–planar structure of the cis-[AuS2Cl2] chromophores shows the low-spin dsp2-hybrid state of the central gold atom. Pairwise secondary interactions Au⋅⋅⋅S between the adjacent molecules in complexes I and III result in the building of zigzag polymer chains (⋅⋅⋅[Au{S2CN(CH3)2}Cl2]⋅⋅⋅)n and binuclear aggregates [Au{S2CN(CH2)6}Cl2]2 at the supramolecular level. Complex II is presented by discrete molecules [Au{S2CN(iso-C3H7)2}Cl2]. According to the simultaneous thermal analysis data, the single final product of the thermolysis of compounds I–III is reduced elemental gold.
