[Si{(NBuᵗ)₂C₂H₄}]

Formula Unicode styled:

[Si{(NBuᵗ)₂C₂H₄}]

Compound name(s):

1,3-Di-t-butyl-1,3,2-diazasilolidin-2-ylidene

Central atom:

Silicon

Charge on formula unit (QN):

Attached groups:

(NBuᵗ)₂C₂H₄ (N,N'-di-t-butyl-ethylenediamino)

Compound type:

Molecular

Notes:

The two nitrogen groups each donate one electron to the silicon in σ bonds. The silicon receives two electrons from the two nitrogen groups that act together as a set classified as an L π function. This takes the EN for silicon to 8.
