Abstract

NHC^MeSiCl₄ (NHC^Me = 1,3-dimethylimidazolidin-2-ylidene) was used to synthesise novel NHC^Me–Pt(II) complexes. An atypical trans–cis isomerisation process was also achieved for [(NHC^Me)₂PtCl₂], while the synthesis of the unique double-complex salt [(NHC^Me)Pt(cod)Cl] [(NHC^Me)PtCl₃] (cod = 1,5-cyclooctadiene) revealed the first-ever N-heterocyclic carbene analogue of the Cossa's salt anion.
