Description:
This thesis deals with the bonding situation of low valent tetrels. More precisely an experimental charge density study of the silylone (cAACcy)2Si was carried out in order to investigate whether the bonding in this new type of molecule is best described by the dual donor-acceptor bond or if silylones should be considered silicon congeners of allenes, showing cumulated double bonds. Furthermore, this work focuses on the improvement of the precision, reliability and validity of charge density studies of such complex organometallic molecules. I...
