TLDR
In this article, the Madelung Part of Lattice Energy (MAPLE) is calculated and discussed, and the MADELung-Anteil der Gitterenergie wird berechnet und diskutiert.Abstract:
Nach Einkristalldaten (137 h 01, h 11, h 21; Mo—Kα) kristallisiert Li2CuO2 (weinrote Kristalle) orthorhombisch mit a = 3,663, b = 2,863, c = 9,396 A, Z = 2, D—Immm mit Li in (4j), Cu in (2b), O in (4i) und z = 0,293, z = 0,3565. Der Madelung-Anteil der Gitterenergie (MAPLE) wird berechnet und diskutiert.

Oxometallates with Planar Coordination
TL;DR: The present state of this research area provides a wealth of interesting principles concerning one-, two-, and three-dimensional linkage of square-planar structural units as mentioned in this paper, and in certain cases the environment of these units in solids requires new conceptual models for chemical bonding.
