✦ Synopsis

“Magnetochcmical series”, not only for ligands but also for central ions, can be drawn up in the case of alkali‐metal lanthanoid oxides or halides. To explain the magnetic behavior of these compounds use was made, inter alia, of the Angular Overlap (AO) model. The AO parameter e~0~(R) could be determined for some series of compounds (from susceptibility measurements). Taking into account the (calculated) overlap integrals S(R) and additional relationships afforded magnetochemical series of the ligands I^−^< Br^−^< Cl^−^< F^−^ ≈ O^2−^ and of the lanthanoids. The sequence of the latter series Corresponds to the pattern of lanthanoid contraction.
