20.500.12556/DKUM-27442 Crystal-structure and Mössbauer studies of Li[sub]1.746]Nd[sub]4.494FeO9[sub]9.493 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. crystal structure ternary compounds single-crystal X-ray diffraction Mössbauer spectroscopy iron oxidation state kristalna struktura ternarne spojine rentgenska difrakcija Mössbauerjeva spektroskopija rentgenska strukturna analiza true false false Angleški jezik Angleški jezik Neznano 2012-06-01 11:15:00 2012-06-01 11:15:00 2022-04-15 03:44:28 2019-07-10 12:17:10 2007 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 548.73 10850838 0022-4596 URN:SI:UM:DK:C1HYB2UY http://dx.doi.org/10.1016/j.jssc.2006.08.029 1 https://dk.um.si/Dokument.php?lang=slv&id=36742 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
