Intercalation Compounds of FeOCl. Systematics of Amine Containing Lewis Base Intercalants

Abstract

New intercalated compounds of FeOCl and aniline derivatives were synthesized by soaking FeOCl in ethanol solution containing Lewis base intercalants. Only those Lewis base intercalants whose acid-dissociation constant is greater than 5 intercalate into the lattice of FeOCl. The acid-strength of the solvent is important for the formation of an intercalation compound. The intercalates of iron(III) chloride oxide FeOCl(G)1⁄n have been characterized by elemental analysis, powder pattern of X-ray diffraction, Fe-57 Mössbauer and infrared spectroscopies. The research on expansion of the b-axis of the unit cell and IR data confirm the location of the “guest” molecule within the van der Waals layer or the FeOCl lattice. Effective vibrating mass and lattice temperature derived from the Mossbauer spectra are affected by chemical bonding in the first coordination sphere of the iron atom.

Cationically Substituted Bi0.7Fe0.3OCl Nanosheets as Li Ion Battery Anodes

“…Scheme compares the crystal structure of BiOCl and FeOCl. BiOCl has a lattice parameter of 7.34 Å along [001] direction and FeOCl has a lattice parameter of 7.95 Å along [010] direction . The lattice parameter difference between BiOCl (001) and FeOCl (010) is only 7.3%, thus raising the possibility of successful Fe 3+ substitution into the BiOCl lattice.…”
