Abstract
Rare-earth molybdenum-containing oxides of the nominal composition LixNd\(_{{5-x}}\)Mo3O\(_{{16\, \pm \,\delta }}\) (x = 0, 0.05, 0.15, 0.25) with a fluorite-related structure have been obtained for the first time as single crystals grown from flux and by solid-phase synthesis in air in the form of polycrystalline samples. The new phases are characterized using X-ray diffraction analysis, simultaneous thermal analysis, and impedance spectroscopy. X-ray diffraction analysis showed that lithium atoms are localized near the positions of rare-earth cations. The chemical formula of the investigated single crystal is Li0.216Nd4.784Mo3O\(_{{14.1 + \delta }}\). The low lithium content did not affect significantly the ability of the studied phases to dissociative absorption of water but led to a decrease in the total conductivity of LixNd\(_{{5-x}}\)Mo3O\(_{{16\, \pm \,\delta }}\) lithium ceramics.
期刊介绍：
Crystallography Reports is a journal that publishes original articles short communications, and reviews on various aspects of crystallography: diffraction and scattering of X-rays, electrons, and neutrons, determination of crystal structure of inorganic and organic substances, including proteins and other biological substances; UV-VIS and IR spectroscopy; growth, imperfect structure and physical properties of crystals; thin films, liquid crystals, nanomaterials, partially disordered systems, and the methods of studies.
