The Pt(II) centres in trans-[PtCl(μ-Cl) (PEt3)]2 were shown to be able to abstract sulfinyl-containing Lewis bases from several of their Sn(IV) adducts and form stable Pt(II) complexes. Hexacoordinate Sn(IV) adducts of Ph2SnCl2 with disulfoxides of the type (RSOCH2)2 (R=Pr, Ph), as well as with 1-methyl-2-(methylsulfinyl) imidazole (ImSOMe), had the sulfur-containing ligand abstracted by Pt(II) to form either S-bonded bridging diplatinum complexes (in the case of the disulfoxides) or an N-bonded species (with ImSOMe), as shown by spectroscopic and structural analysis. The ligand abstraction seems to be a general reaction. Only when the Sn(IV) precursor was changed to the particularly stable MeSnCl3-ImSOMe complex, in which the tin moiety is strongly acidic, did the reaction not proceed.
