Abstract
Lithium has been intercalated into FeMoO4Cl, and deintercalated from LixFeMoO4Cl both electrochemically and chemically. The inserted Li+ ions are stabilized in the distorted octahedral field in interlayer space of FeMoO4Cl. The crystal symmetry is reduced from tetragonal to monoclinic due to the reduction of ferric to ferrous ions in LixFeMoO4Cl upon lithium intercalation. From the magnetic and structural data, it has been concluded that the high-spin electronic configuration of Fe2+(d2xzd1yzd1xyd1z2d1x2-y2), corresponding to 5Eg, group term in D4h symmetry, can be stabilized by the elongation of FeO4Cl2-octahedra in a weak ligand field.
