Complexes with S-donor ligands. Part 2. Synthesis of anionic bis(thiolato)gold(I) complexes. Crystal structure of [N(PPh3)2][Au(SR)2](R = benzoxazol-2-yl)

Abstract

The reaction of [N(PPh₃)₂][Au(acac)₂](Hacac = acetylacetone) with HSR gave acetylacetone and the complexes [N(PPh₃)₂][Au(SR)₂][HSR = benzoxazole-2(1H)-thione 1, pyrimidine-2(1H)-thione 2, pyridine-2(1H)-thione 3, 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranose 4, 2-thiouracil (2,3-dihydro-2-thioxo-1H-pyrimidin-4-one)5, 2,3-dihydro-1H-benzimidazole-2-thione 6, 2-thiomailc acid 7, 2-sulfanylethanol 8, D-penicillamine (3-sulfanylvaline)9]. The crystal structure of 1 has been solved. The gold atom adopts the usual linear co-ordination [175.11(5)°] and the Au–S bond distances are normal [2.281 (2) and 2.283(2)Å].
