1,4-Bis(diphenylphosphanylmethyl)benzene (1) was converted into its bis complex upon treatment with two equivalents of chloro(dimethyl sulfide)gold(I).The reaction of 1*(AuCl)2 with one equivalent of silver tetrafluoroborate afforded a cyclic dichloronium tetrafluoroborate .Substitution of chloride in 1*(AuCl)2 by sodium methanethiolate in wet chloroform, gave the bis complex 1*(AuSMe)2, while with sodium sulfide a cyclic complex 1*Au2S was obtained.Reaction of 1*(AuCl)2 with two equivalents of AgBF4 followed by treatment with diphenyldisulfide or sodium methanethiolate yielded the cyclic methyl/phenylsulfonium tetrafluoroborates 1*Au2SPh(1+)BF(1-) and 1*Au2SMe(1+)BF4(1-), respectively.All compounds were identified on the basis of their analytical and spectroscopic data.The crystal structures of 1*(AuCl)2, 1*(AuSMe)2, and 1*Au2S have been determined.The Au2S complex has a cyclic structure with a narrow Au-S-Au angle of 86.7(1) deg indicating a significant intraannular Au...Au interaction. - Keywords: Gold sulfide complexes / Gold thiolates / (Phosphane)gold(I) complexes / Digoldsulfonium salts / Digoldchloronium salt
