Abstract

(Figure Presented) Following orders: The cobalt and niobium ions in Ba 8CoNb6O24 are completely ordered in the seven-layer repeat of hexagonal and cubic stacking. Such site-ordered solids may find application as microwave dielectric resonators, for example, in mobile telecommunications. In the structure shown, {CoO6} and {NbO 6} units are red and blue octahedra, respectively, and barium cations are black spheres.
