Tetrahydrothiophene, Disulfonylamine
The molecular gold(I) complexes di(methanesulfonyl)amido-N-(tetrahydrothiophene)gold(I) (1), di(p-chlorobenzenesulfonyl)amido-N-(tetrahydrothiophene)gold(I) (2), and di(p-iodobenz- enesulfonyl)amido-N-(tetrahydrothiophene)gold(I) (3), were synthesised from (tetrahydrothio- phene)chlorogold(I) and the appropriate silver salt. Crystal structure analyses were performed for all three compounds (3both solvent-free and as a dichloromethane solvate3a) and revealed a variety of intermolecular contacts. Compound1crystallizes with four independent molecules, two of which are connected by a gold-gold interaction of 3.2869(8) ˚A; several short non- classical hydrogen bonds of the form C-HO (the shortest with HO 2.31 ˚A) are observed. In compound2, cyclodimers are formed via AuAu contacts of 3.3302(8) ˚A; additionally ClCl contacts of 3.457(3) ˚A are observed. Both forms of compound3are characterized by AuI contacts, somewhat longer in3(3.6 - 4.3 ˚A) than in3a(3.4 - 3.5 ˚A). The di(arenesulfonyl)amide ligands in2,3and3adisplay approximate C2symmetry.
