Both and ClO4, followed by deprotonation with NaH> and the free methanide SPPh2CHPPh2Me react with gold(I) or silver(I) complexes (tht = tetrahydrothiophene), ClO4, and to afford binuclear complexes of the types PPh2Me>> or <2>2 (M = Au or Ag).The silver complex can also be obtained by deprotonation of <2>2 with Na2CO3.Oxidative addition of chlorine to the gold derivative giv es the binuclear gold(II) complex <2>.The structure of PPh2Me>> has been established by X-ray crystallography 1/c, with a = 15.392(4), b = 12.643(5), c = 21.965(7) Angstroem, β = 107.95(2) deg, and R' = 0.072 for 3 166 unique observed reflections>.The molecule adopts a folded conformation with parallel, eclipsed C6F5 rings and a corresponding short Au...Au contact of 3.224 Angstroem.
