Resumo

The 1 : 1 adduct of the PtI–PtI dimer [Pt-µ-{o-C6H4P(Ph)CH2 CH2PPh2}]2 with methyl iodide is deprotonated by sodium methoxide to give a µ-methylenediplatinum(II) complex [Pt2-µ-{o-C6H4P(Ph)CH2CH2PPh2}2(µ-CH2)], characterised by single-crystal X-ray structural analysis; the latter complex reacts with [Me3O]PF6 to give an ethyldiplatinum(II) cation which retains the bridging cyclometallated dppe ligands.
