Br)(μ-Br)BrHg(EtS(CH2)2SEt)] · 2HgBr2 (5), which has been characterized by single crystal structure determination and 1H and 13C1H} NMR spectra. The elemental tellurium and [C4H3SCH2]2 are the other products of dissociation as identified by NMR (proton and carbon-13). The cleavage appears to be without any transmetalation and probably first of its kind. The centrosymmetric structure of 5 is unique
