Lithium intercalation in FeOCl revisited

The reaction of iron oxychloride with n-butyl-lithium has been re-examined, important changes being found in the structure and properties of the lithiated compounds as compared to the pristine material. Lithium intercalation by these means increases several orders of magnitude the electrical conductivity of FeOCl although the intercalate remains semiconductor. From the structural and microstructural point of view the lithiation results in complex changes, including inter alia staging, superstructures, etc., and it seems to be quite an heterogeneous process.
