Crystal structure of benz-yl(meth-yl)phen-yl[(piperidin-1-ium-1-yl)meth-yl]silane bromide.
The title compound, C20H29NSi(+)·Br(-), contains a chiral silicon atom but crystallizes as a racemate. The C-Si-C bond angles in the range of 103.64 (8)-111.59 (9)° are usual for tetra-hedral geometry. The piperidine ring shows a regular chair conformation with an equatorially positioned exocyclic N-C bond. In the crystal, there is a hydrogen bond between the ammonium cation and the bromide anion. The crystal packing shows the dominant inter-molecular inter-action to be the electrostatic attraction between the ammonium cation and the bromide anion.
