Abstract
The reaction of [Pt2(μ-Se)2(PPh3)4] with diphenyliodonium bromide gave [Pt2(μ-Se)(μ-SePh)×(PPh3)4]+ through arylation of a selenide ligand. The complex is characterised by 31P NMR spectroscopy, elemental microanalysis, ESI mass spectrometry, and a single crystal X-ray diffraction study, which showed the four-membered {Pt2Se2} ring to be slightly puckered.
