Synthesis and characterization of gold(I) and gold(III) thione complexes
摘要:
[AuCl],H[AuCl4] or [AuCl3] react with various thiones to form stable complexes of the type [AuCl(thione)] or [AuCl3(thione)]in high yields. The products were characterized by H-1 NMR, IR and UV spectroscopy and by determining the crystal and molecular structures of [AuCl(S = CSCH2CH2S)] and [AuCl3(S = CHNMe2)]. Due to large standard deviations it is not possible to differentiate between the two Au-S distances [2.258(4) and 2.296(12) angstrom].
