The Ag_0.62K_0.38Nb₄AsO₁₃ compound was prepared by a solid state reaction. A qualitative analysis by scanner electronic microscope (S.E.M) and infrared (I.R) spectroscopic study were made for the state. The structural study of the Ag_0.62K_0.38Nb₄AsO₁₃ compound shows that this material crystallizes in the orthorhombic system (space group Cmcm) and has a three dimensional framework. There are tunnels, with hexagonal section, in where Ag⁺ and K⁺ cations are located. The characteristics derived from the structural study, which support good ion mobility, have encouraged to study the ionic conductivity through the complex impedance method.
