Montmorillonite: electron diffraction from two-dimensional single crystals.
Some Selected area electron diffraction patterns of isolated monocrystalline particles of both Wyoming and Camp Berteaux sodiumti-monfmorillonites fail to show the mirror platne symmetry required for the accepted structure. A triclinic model deserves consideraction.
