Title: Crystal-structure and Mossbauer studies of Li{sub 1.746}Nd{sub 4.494}FeO{sub 9.493}

Abstract

The Li{sub 1.746}Nd{sub 4.494}FeO{sub 9.493} (LNF) ternary phase, located in the Li{sub 2}O-rich part of the Li{sub 2}O-Nd{sub 2}O{sub 3}-Fe{sub 2}O{sub 3} system, crystallizes with a cubic unit cell of dimension a=11.9763(3)A and the space group Im3m. Refinement on F resulted in R=1.9%. The structure is comprised of a network of corners, edges and faces sharing the coordination polyhedra of neodymium. In between this skeleton the regular octahedra of oxygen-coordinated iron and trigonal prisms of lithium are located. The Mossbauer spectra revealed the presence of Fe{sup 3+}, Fe{sup 4+} and Fe{sup 5+} ions distributed on two symmetry-independent lattice positions.
