“…First one is an ionic conductor having an averaged structure such as AgI above 419 K, in which one Ag + cation occupies six positions statistically. Similar averaged structures have been observed for two-dimensional conductors, such as β-alumina [1], PbSnF 4 [2,3] and MSn 2 F 5 (M = K and Rb) [4][5][6]. These liquid-like ionic conductivities are normally associated with the dynamical disorder of the relevant ions at the elevated temperature phases.…”

As shown above, the tetragonal PbSnF 4 [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] is known as a fluoride ion conductor having high electric conductivity at ambient temperature. The CO 2 /F 2 electrochemical cell was constructed using tetragonal PbSnF 4 with Au electrodes as the solid electrolyte; its performance was investigated using emf and impedance measurements.…”

“…along one of the pseudocubic h1 0 0i axes leading to tetragonal symmetry (space group P4/nmm [77]). While the anions between the two Pb 2 þ layers lie close to the tet sites occupied within the equivalent fluorite structure, the Sn 2 þ -Sn 2 þ layers are essentially empty [77,78]. The displaced anions are located within the Pb 2 þ and Sn 2 þ sheets, leading to a highly disordered arrangement of F À .…”

Superionic conductors are solids which show high levels of ionic conductivity, which often approach values more typical of ionic liquids. This behavior is associated with the presence of extensive dynamic disorder within the crystalline lattice, and the nature of the defects has long proved a challenge to both experimental and computational approaches. This chapter provides a short introduction to the major techniques used to probe the structure-property relationships within superionic conductors, highlighting the roles of X-ray diffraction, neutron diffraction, EXAFS, NMR, and molecular dynamics methods. The relative advantages and limitations of each method are briefly described, followed by a discussion of the major families of highly conducting compounds and an assessment of the current state of knowledge concerning their structural properties. OverviewThe high levels of ionic conductivity associated with superionic conductors, which often approach values more typical of ionic liquids, are associated with the presence of extensive dynamic disorder within the crystalline lattice. As a consequence, a full understanding of the interplay between the structural and conducting properties of these important materials requires a detailed characterization of both the long-range arrangement of the ions within the crystal lattice and the short-range ion-ion correlations within the defects. The presence of significant levels of disorder, which can be both intrinsic (thermally induced) and extrinsic (due to chemical doping) in origin, presents a challenge to the conventional experimental methods used to provide structural information. In the case of superionic conductors, no one technique can provide a complete picture, and it is often necessary to employ several complementary approaches, of which X-ray diffraction (XRD), neutron diffraction, Solid State Electrochemistry I: Fundamentals, Materials and their Applications.
