An N‐Heterocyclic Silylene‐Stabilized Digermanium(0) Complex

The synthesis of an N‐heterocyclic silylene‐stabilized digermanium(0) complex is described. The reaction of the amidinate‐stabilized silicon(II) amide [LSiN(SiMe 3 ) 2 ] ( 1 ; L=PhC(N t Bu) 2 ) with GeCl 2 ⋅dioxane in toluene afforded the Si II –Ge II adduct [L{(Me 3 Si) 2 N}Si→GeCl 2 ] ( 2 ). Reaction of the adduct with two equivalents of KC 8 in toluene at room temperature afforded the N‐heterocyclic carbene silylene‐stabilized digermanium(0) complex [L{(Me 3 Si) 2 N}Si→ GeGe←Si{N(SiMe 3 ) 2 }L] ( 3 ). X‐ray crystallography and theoretical studies show conclusively that the N‐heterocyclic silylenes stabilize the singlet digermanium(0) moiety by a weak synergic donor–acceptor interaction.
