Abstract

The interaction of freshly precipitated binuclear [Zn₂(S₂CNPr₂)₄] with an H[AuCl₄]/2 M HCl solution has afforded the dipropyldithiocarbamato-chlorido complexes of gold(III): ionic [Au(S₂CNPr₂)₂][AuCl₄] (1) and molecular [Au(S₂CNPr₂)Cl₂] (2) ones, the structural organization of which has been elucidated using single-crystal XRD. Supramolecular self-assembly of the complexes involving multiple non-covalent interactions (secondary bonds Au···S, S···Cl and non-classical hydrogen bonds C–H···Cl) leads to the formation of 2D pseudo-polymeric layers. In a solution, ionic complex 1 tends to undergo gradual spontaneous transformation into molecular compound 2. The only final product of thermal decomposition of the considered compounds is microcrystalline elemental gold.

二硫代氨基-氯代金（III）配合物[Au(S2CNPr2)2][AuCl4]和[Au(S2CNPr2)Cl2]：结构组织、溶液中的相互转化和热行为

新沉淀的双核[Zn2(S2CNPr2)4]与H[AuCl4]/2 M HCl溶液相互作用，得到了金（III）：离子[Au(S2CNPr2)2][AuCl4](1)和分子[Au(S2CNPr2)Cl2](2)的二丙基二硫代氨基-氯配合物，并用单晶XRD对其结构组织进行了分析。配合物的超分子自组装涉及多个非共价相互作用（二级键Au··S， S··Cl和非经典氢键c·h·Cl），导致二维伪聚合物层的形成。在溶液中，离子络合物1倾向于逐渐自发转化为分子化合物2。所考虑的化合物热分解的唯一最终产物是微晶单质金。

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
