Abstract

A complex of vermiculite with ethylene glycol was prepared by repeated boiling of a sodium-saturated cleavage flake in dry ethylene glycol. A stable product with a c period of 12.9 Å afforded 15 terms for a one-dimensional Fourier synthesis. A model composed of glycol molecules with the plane of the zigzag normal to the silicate face is found to be consistent with the observed diffraction data. The complex apparently conforms to a stoichiometric ratio of two molecules per unit cell per layer of vermiculite.
