Abstract
The interaction of AuCl4- with thiourea (tu) at various Сtu/СAu 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.
