Transformations of the Bis(thiourea)gold(I) Complex in Alkaline Medium and Interaction of Thiourea with HAuCl4

详细

The interaction of AuCl₄^- with thiourea (tu) at various С_tu/С_Au ratios and transformations of the bis(thiourea)gold(I) complex in an alkaline aqueous solution have been studied. Both processes lead to a set of products. It has been demonstrated that formamidine disulfide is not the major product of thiourea oxidation. The precipitate forming upon the treatment of AuCl₄^- with an alkali contains Au₂S and an organic part, which is likely a polymeric compound [Au(tu-H)]_n.
