Abstract:	The $Li_1.746Nd_4.494FeO_9.493$ (LNF) ternary phase, located in the $Li_2O$ -rich part of the $Li_2O-Nd_2O_3-Fe_2O_3$ system, crystallizes with a cubic unit cell of dimension 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 Mössbauer spectra revealed the presence of $Fe^3+$ , $Fe^4+$ and $Fe^5+$ ions distributed on two symmetry-independent lattice positions.
