The reaction of (dimethylsulfide)gold(I) chloride and bromide with methyl(phenyl)phosphine in tetrahydrofuran affords high yields of the colorless, crystalline, chiral complexes AuCl/Br (1a,b).Treatment of 1a with potassium iodide in thf leads to a conversion into the corresponding iodide AuI (1c).The compounds were characterized by their analytical and spectroscopic data, and the crystal structures of 1a, b have been determined.The two compounds are isomorphous.In the lattice the monomers form chain-like supramolecular aggregates through auriophilic Au-Au contacts.The chains contain both enantiomers following the sequence ..R S R S R S ... with the individual components related by crystal symmetry. - Key words: Gold(I) Complexes; Chiral Phosphine Ligands; Auriophilicity; Supramolecular Aggregates
