N2 - The interactions of SCN- and SeCN- with aurothiomalate [Au(tm)]n in aqueous solution were studied by 13C NMR spectroscopy. The [Au(tm)]n is further polymerized in the presence of SCN-, however, SeCN- binds to [Au(tm)]n forming monomeric [Au(SeCN)(tm)]-. This complex initially disproportionates to give [Au(SeCN)2]- and [Au(tm)2]-. The [Au(SeCN)2]- eventually decomposed to give [Au(CN)2]- and metallic selenium. The free tm- released from [Au(tm)]n is oxidized to the thiomalic disulfide (tm)2. When the bis complex [Au(tm)2]- reacted with SeCN- it did not form [Au(SeCN)(tm)]-, but instead gave (tm)2, [Au(CN)2]- and Se22-.
