A new type of Si(II) : A novel silylene stabilized by a Cp* and an imidazolin‐2‐iminato ligand has been prepared using two different methods (see scheme). The X‐ray crystallographic structure shows that the silicon(II) center is coordinated to an η 2 ‐Cp* ligand and the nitrogen atom of an imidazolin‐2‐iminato ligand. This silylene easily reacts with B(C 6 F 5 ) 3 to give a stable borane adduct having a zwitterionic resonance structure.
