On ‘seeing’ the stacking sequence in graphite–iron(III) chloride intercalates by high-resolution electron microscopy

Abstract

Lattice images of iron(III) chloride intercalate residue compounds, when recorded with their layer planns parallel tothe electron beam, reveal the occurrence of coherent intergrowths of the so-called first-, second-, fifth-, and sixth-stage intercalates in which a sheet of FeCl₃, is inserted between, respectively, all, every second, every fifth, and every sixth individual sheet of carbon.
