Two new iron(IV) oxides with high-spin configuration SrLaMg/sub 0. 50/Fe/sub 0. 50/O/sub 4/ and SrLaZn/sub 0. 50/Fe/sub 0. 50/O/sub 4/*

Two new iron(IV) oxides have been prepared using high oxygen pressure: SrLaM/sub 0.50/Fe(IV)/sub 0.50/O/sub 4/ (M = Mg, Zn). In both phases with a K/sub 2/NiF/sub 4/-type-derived structure the elongation of the (FeO/sub 6/) octahedron is sufficient to stabilize a high-spin state (t/sub 2g//sup 3/d/sub z//sup 1/2). The electronic configuration has been characterized by structural, magnetic, and Moessbauer spectroscopic investigations.
