STRUCTURAL AND MASS SPECTROMETRIC CHARACTERISATION OF THE DINUCLEAR PLATINUM(II) SELENIDO-PHENYLSELENOLATO COMPLEX [Pt <sub>2</sub>(m-Se)(m-SePh)(PPh <sub>3</sub>) <sub>4</sub>]PF <sub>6</sub>
The reaction of [Pt <sub>2</sub>(m-Se) <sub>2</sub>(PPh <sub>3</sub>) <sub>4</sub>] with diphenyliodonium bromide gave [Pt <sub>2</sub>(m-Se)(m-SePh)×(PPh <sub>3</sub>) <sub>4</sub>] <sup>+</sup> through arylation of a selenide ligand. The complex is characterised by <sup>31</sup>P NMR spectroscopy, elemental microanalysis, ESI mass spectrometry, and a single crystal X-ray diffraction study, which showed the four-membered {Pt <sub>2</sub>Se <sub>2</sub>} ring to be slightly puckered.
