Intercalation of organometallic compounds into layered transition metal oxyhalides

The syntheses of the new intercalate compounds FeOCl[(EtMe4Cp)2Fe]0.16, VOCl(CoCp2)0.16, and TiOCl(CoCp2)0.16 are reported. Their structures are found by X-ray powder diffraction to be qualitatively the same as those of the previously reported complexes FeOCl(CoCp2)0.16 and FeOCl(FeCp2)0.16. Results of 57Fe Mössbauer and magnetic susceptibility studies on the latter two compounds are reported, and shown to be consistent with electron transfer from the metallocene to the host upon intercalation.
