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.

Mononuclear palladium and platinum complexes of the type M(ER)2(P∩P) [M = Pd or Pt; ER = SPh, SC6H4Cl-4, SC6H4Me-4, SC6F5, SePh, TeC6H4OEt-4; P∩P = dppm or dppe] have been prepared and their ability to form dinuclear metal species has been demonstrated. All complexes have been characterised by multinuclear magnetic resonance (1H, 13C, 77Se, 195Pt) spectral data. The effects of phosphine ligands and organochalcogenides are reflected in the 77Se and 195Pt NMR shifts. The shielding of 195Pt NMR chemical shifts has been interpreted in terms of their binding ability to platinum. The structures of two derivatives, namely [Pd(SC6F5)2(dppe)] and [Pd(SePh)2(dppe)], have been established by X-ray crystallography. The palladium atom in each of the monomeric structures exists in a square planar geometry.

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.
