The new mononuclear palladium(II) and platinum(II) [M(p-SC6F4(CF3))2(dppe)] complexes M = Pd 1a, Pt 2a; [M(o-SC6H4(CF3))2(dppe)] M = Pd 1d, Pt 2d as well as the previously known [M(SC6F5)2(dppe)] M = Pd 1b, Pt 2b and [M(p-SC6HF4)2(dppe)] M = Pd 1c, Pt 2c, have been used as metalloligands for the preparation of the heteroleptic bimetallic complexes [M2(μ-SRf)2(dppe)2](SO3CF 3)2 M = Pd, Rf = p-C6F4(CF3) 3a, C6F5 3b, p-C6HF4 3c, o-C6H4(CF3) 3d; M = Pt, Rf = p-C6F4(CF3) 4a, C6F5 4b, p-C6HF4 4c and o-C6H4(CF3) 4d. Variable temperature 19F NMR experiments show that the fluorothiolate bridged bimetallic compounds are fluxional in solution whereas mononuclear complexes are not. The solid state X-ray diffraction structures of [Pd(p-SC6HF4)2(dppe)] (1c), [Pt(SC6F5)2(dppe)] (2b) and [Pt(o-SC6H4(CF3))2(dppe)] (2d) show square-planar coordination around the metal centers. The solid state molecular structure of the compound [Pt2(μ-o-SC6H4(CF3)) 2(dppe)2](SO3CF3)2 (4d), exhibit a planar [Pt2(μ-S)2] ring with the sulfur substituents in an anti configuration.
Stereospecific reactions of the "M(C6F5)2" (M = Pd or Pt) synthons towards cis-dithiolato complexes

Complexes of the general formula cis- (M=Ni, Pd, or Pt; L2=dppm , dppe , or 2PPh3) were synthesized by the reaction (1 : 2) between the corresponding cis- and Tl(SC6F5).When treated with cis- (M=Pd or Pt; THF=OC4H8) they yield geminal homo- or hetero-binuclear compounds, which were characterized by IR, NMR and mass spectroscopy.
