Dalton communications. New co-ordination mode of 4,5-dimercapto-1,3-dithiole-2-thionate(2–) in polynuclear gold(I) complexes. Crystal structures of [Au3(µ3-C3S5)(PPh3)3] ClO4 and [Au4(µ-C3S5)2(µ-Ph2PCH2PPh2)2]
Abstract
The ligand 4,5-dimercapto-1,3-dithiole-2-thionate(2–)(C3S52–) has been transferred from [Net4]2-[Zn(C3S5)2] to gold(I) centres, affording di-, tri- or tetra-nuclear complexes containing the C3S52– ligand in unprecedented µ- or µ3-bridging forms.
