Abstract

Molecule with three faces. Two of the three possible configurations that a stable silicate with five carbon substituents can adopt have been observed by NMR spectroscopy and shown to be in dynamic equilibrium through a Berry pseudorotation. The thermodynamics and kinetics of their exchange are in good agreement with calculations. The major configuration (from the crystal structure of the nBu₄N⁺ salt) is shown in the center of the picture.
