Quantum chemical calculations have been carried out at the BP86/TZ2P+ level for the compounds SiC(L) 2 with L=NHC Me , CAAC Me , PMe 3 (NHC=N‐heterocyclic carbene, CAAC=cyclic (alkyl)aminocarbene). The optimized geometries exhibit a trans arrangement of the ligands L at SiC with a planar coordination when L=NHC Me and PMe 3 , while a twisted conformation is calculated when L=CAAC Me . The bending angle L‐Si‐C is significantly more acute than the angle L‐C‐Si. Both angles become wider with the trend PMe 3
