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.
