Three benzyl silanes, 1-(benzyldimethylsilyl)methyl-1-methylpiperidin-1-ium iodide (1), 1(dibenzyl-methylsilyl)methyl-1-methylpiperidin-1-ium iodide (2) and 1-(2-(benzyldimethyl-silypethyl)-1-methyl-piperidin-1-ium iodide (3), have been synthesized and structurally characterized by X-ray crystallography. Compounds 1 and 2 are evaluated to determine what structural influence the positive charge in alpha-position to silicon has on the silicon atom. Furthermore, the compound 3 is used to compare this effect and to show the structural and electronic differences in comparison to 1 and 2. DFT calculations were performed to investigate the individual electronic environments of the silicon and surrounding atoms in detail, which are discussed in regards to Bent's rule (Bent, 1960, 1961).
