Abstract:The structure of the perovskite compound Srurn:x-wiley:00442313:media:ZAAC19703780202:tex2gif-stack-4 NiIITeVI (6)O6 (1:1 order in the octahedral sites) is described in detail. The obtained Ni? O distance (2.04 Å aTe–O = 1.91 Å) together with that one within the corresponding tungsten perovskite (part II) will be analyzed quantitatively with respect to the connection between structure and ligand-field as well as EPR data. The comparison of this distance and the spectroscopic results of the tellurium perovskite with corresponding data of NiII-doped MgO however shows already now that an interpretation on the basis of an ionic model is impossible
