Gold(I) complexes with t-butyl phosphine and dialkyl dithiocarbamate ligands

摘要

Gold(I) complexes of formulae [Au{P(t-Bu)3}(S2CN(CH3)2)] (1), and [Au{P(t-Bu)3}(S2CN(C2H5)2)] (2) have been prepared by the reaction of equimolar amounts of [Au{P(t-Bu)3}(Cl)] with sodium dimethyldithiocarbamate monohydrate, and sodium diethyldithiocarbamate trihydrate respectively. Both complexes (1) and (2) are iso-structural having linear geometry. These gold(I) dithiocarbamate complexes show in vitro cytotoxic activities against A549 (human lung carcinoma), HeLa (human cervical cancer) and MCF7 (human breast cancer) cell lines.
