Pentacoordinate silicon(<scp>iv</scp>): cationic, anionic and neutral complexes derived from the reaction of NHC→SiCl<sub>4</sub> with highly Lewis acidic (C<sub>2</sub>F<sub>5</sub>)<sub>2</sub>SiH<sub>2</sub>
afforded the salt [(NHC)2SiCl2H][(C2F5)2SiCl3] with pentacoordinatesilicon in the cation and the anion. The anion represents the first example of a chlorosilicate structurally characterized in the solid state. In this reaction, the long sought pentacoordinate NHC-adduct of silicochloroform was identified as an intermediate and its crystal structure is presented.

NHCMeSiCl4 was used to selectively synthesise cis and trans-[(NHCMe)2PtCl2], as well as [NHCMePt(cod)Cl][NHCMePtCl3], which revealed the first ever N-heterocyclic carbene analogue of the Cossa's salt anion.
