A stable, mononuclear, cationic Pt(iii) complex stabilised by bulky N-heterocyclic carbenes†
Abstract
The thermally stable, paramagnetic Pt(III) complex [PtI2(IPr)2][BArF] has been prepared by oxidation of the Pt(II) complex [PtI2(IPr)2] with iodine in the presence of NaBArF. X-ray crystallographic studies revealed the mononuclear nature of this species with a square-planar geometry. EPR and DFT studies pointed out to a metal-centred radical.
