ScholarBank@NUS Repository. https://doi.org/10.1016/j.jorganchem.2008.09.013 | Abstract: | Reaction of the metalloligand [Pt2(μ-S)2(PPh3)4] with 0.5 mol equivalents of durene-1,4-bis(mercuric acetate) [AcOHgC6Me4HgOAc] in methanol gives the polynuclear complex [{Pt2(μ-S)2(PPh3)4}2 (μ-1,4-C6Me4Hg2)]2+ , isolated as its PF6 - and BPh4 - salts. Positive-ion ESI mass spectra indicate that [{Pt2(μ-S)2(PPh3)4}2 (μ-1,4-C6Me4Hg2)]2+ undergoes fragmentation by successive loss of PPh3 ligands, while the ESI mass spectrum of the BPh4 - salt showed additional ions [Pt2(μ-S)2(PPh3)4 (HgC6Me4HgPh)]+ and [Pt2(μ-S)2(PPh3)4HgPh] + as a result of phenyl transfer from BPh4 - to Hg. A single-crystal X-ray structure determination on [{Pt2(μ-S)2(PPh3)4}2 (μ-1,4-C6Me4Hg2)](BPh 4)2 shows that the cation crystallises on a centre of symmetry, with structural features that are comparable to those of the previously characterised complex [Pt2(μ-S)2(PPh3)4HgPh]BPh 4. © 2008 Elsevier B.V.
