Abstract
The title mol-ecular salt, C17H30NSi+·C2H5O4S-, belongs to the class of a-amino-silanes and was synthesized by the alkyl-ation of 1-[(benzyl-dimethyl-sil-yl)meth-yl]piperidine using diethyl sulfate. This achiral salt crystallizes in the chiral space group P21. One of the Si-C bonds in the cation is unusually long [1.9075 (12) Å], which correlates with the adjacent quaternary N+ atom and was verified by quantum chemical calculations. In the crystal, the components are linked by weak C-H⋯O hydrogen bonds: a Hirshfeld surface analysis was performed to further investigate these inter-molecular inter-actions and their effects on the crystal packing.
