The donor‐stabilized silylene [ i PrNC(N i Pr 2 )N i Pr] 2 Si ( 2 ) reacts with PhEl−ElPh (El=S, Se) to form the respective cationic five‐coordinate bis(guanidinato)silicon(IV) complexes {[ i PrNC(N i Pr 2 )N i Pr] 2 SiSPh} + PhS − ( 4 ) and {[ i PrNC (N i Pr 2 )N i Pr] 2 SiSePh} + PhSe − ( 5 ). Compounds 4 and 5 were characterized by crystal structure analyses and NMR spectroscopic studies in the solid state.
