| description | Crystals of Na3Nb4As3O19 were synthesized by a solid-state reaction. It crystallizes in the orthorhombic system, space group C2221 with a = 13.014(2) Å, b = 24.170(3) Å and c = 5.0880(9) Å. The structure can be described as a three-dimensional anionic framework containing two kinds of tunnels parallel to [001] direction where Na+ cations are located. The ionic conductivity was measured, on pellets of polycrystalline powders, between 573 and 893 K in the frequency range 0.01–13000 kHz through the complex impedance method. A correlation between electrical and structural properties was also discussed. Keywords: Three-dimensional framework, IR spectroscopy, CI spectroscopy, Ionic conductivity |
