Abstract

The oxygen‐deficient SrFeO~2.74~ phase of quenched samples is located within the miscibility gap of the SrFeO~3–δ~ perovskite system, and exhibits a manifold vacancy ordering pattern at room temperature. We have studied the complex ordering by high‐resolution electron microscopy, and by electron and X‐ray diffraction. New principal superlattice structures have been identified by electron diffraction which can be of relevance for the electronic and magnetic properties of this respective perovskite system.

A detailed electron di4raction and XRPD study has been made of the room-temperature polymorph of K 3 MoO 3 F 3 . It is shown that the true symmetry of this polymorph is neither tetragonal, trigonal, nor triclinic as previously reported but rather monoclinic I1a1, a ‫؍‬ 2a p ؊ c p , b ‫؍‬ 4b p , c ‫؍
