1,3-Di-t-butyl-1,3,2-diazasilolidin-2-ylidene
Central atom: 
Charge on formula unit (QN): 
0
Compound type: 
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.
