Oriented aggregates of ethylene glycol-montmorillonite were studied by x-ray diffractometer methods. Basal reflections, through the 00 14, provided the basis for structural analysis by Fourier and trial and error methods. On the basis of the intensity data, it is concluded that glycol molecules form a staggered, two-layered complex; water molecules and exchangeable cations lie close to but not coincident with a plane that separates the two glycol layers. The glycol molecules in each layer are disposed in c-axis face centered array. They are oriented so that the plane of symmetry of the aliphatic chain parallels the c-axis. The proposed structure is a two-layer modification of a previously described glycol-vermiculite structure. /Author/
