Abstract

The molecular gold(I) complexes di(methanesulfonyl)amido-/V-(tetrahydrothiophene)gold(I) (1), di(p-chlorobenzenesulfonyl)amido-/V-(tetrahydrothiophene)gold(I) (2), and di(p-iodobenzenesulfonyl) amido-/V-(tetrahydrothiophene)gold(I) (3), were synthesised from (tetrahydrothiophene) chlorogold(I) and the appropriate silver salt. Crystal structure analyses were performed for all three compounds (3 both solvent-free and as a dichloromethane solvate 3a) and revealed a variety of intermolecular contacts. Compound 1 crystallizes with four independent molecules, two of which are connected by a gold-gold interaction of 3.2869(8) Å; several short nonclassical hydrogen bonds of the form C-H · O (the shortest with H · O 2.31 A) are observed. In compound 2, cyclodimers are formed via Au · Au contacts of 3.3302(8) Å; additionally Cl · Cl contacts of 3.457(3) Å are observed. Both forms of compound 3 are characterized by Au · I contacts, somewhat longer in 3 (3.6 - 4.3 Å) than in 3a (3.4 - 3.5 Å). The di(arenesulfonyl)amide ligands in 2, 3 and 3a display approximate C2 symmetry
