The unusual rearrangement of EPt(L1)](2+) caused by Cl- attack on an alpha
carbon of L1 leading to C-S bond cleavage and formation of a dimer containi
ng both thiolate and thioether donors was investigated by X-ray crystallogr
aphy, NMR and mass spectroscopy. The dimer can also be synthesized from its
constituent ligand precursors.
