Gold-thio-complex

Reed and Spycher (1985) pointed out based on thermochemical calculations that gold does not precipitate due to boiling because pH increases by boiling, leading to an increase in gold solubility due to gold-thio complexes. They indicated that acidification... [Pg.173]

If gold-thio-complex such as Ag(HS)2 is dominant gold species in hydrothermal solution, gold solubility is controlled by the reaction. [Pg.68]

Freeman and coworkers f have reported the reduction of H[AuCU] in aqueous solution by thiourea which yields the gold(I) complex, [Au(thio)2]Cl. Kukushkin, Vorobev-Desyatovskii and Patrabansh have investigated the reactions of the cis and trans isomers of [PtCl4(amine)2] (amine = NH3,... [Pg.308]

It is surprising that transition metal complexes containing ferrocenyl thio-late ligands (FcS) have not been studied in detail so far. The only examples are gold complexes such as (Fc-S)Au(PPh3) [86], [(FcS)Au2(PPh3)2](BF4) [86, 183], [(Ph3PAu-S)fc-S-]2 (Scheme 5-18) [90], and [(FcS)Au(nBu)2]3 [86],... [Pg.252]
