„Kationenreiche”︁ Oxide Die Kristallstruktur von Li3InO3

Li₃InO₃ crystallises trigonal, P3 c1, with a = 9.606₄, c = 10.42₀ Å, c/a = 1.064₇, Z = 12 and In₁ in 2(a), In₂: 4(d), In₃: 6(f), and O₁, O₂, O₃, Li₁, Li₂, Li₃ each in 12 (g). According to Li₂^[4]{In□_1/3}O₂ Li₃InO₃ is a “stuffed derivative” of a layer structure of the CdJ₂ type. Calculations of the Madelung Part of Lattice Energy [MAPLE] assure the localisation of Li by X-Ray work and explain why In₂, O₁, O₂, and O₃ depart from “ideal” positions.
