Abstract

The crystal structure of two new K₂NiF₄-type oxides, SrLaMg_0.5Mn_0.5O₄ and SrLaZn_0.5Mn_0.5O₄, have been determined with space group both 14 mmm and P422 using Rietveld refinement profile. An improvement in reliability factor on the basis of space group P422 suggested that they have ordered structure and unit cell parameters be a ≅ a₀√2 = 5.4428(1) A ̊, c ≅ c₀ = 12.6084(2) A ̊ for SrLaMg_0.5Mn_0.5O₄ and a ≅ a₀√2 = 5.4588(1) A ̊, c ≅ c₀ = 12.6247(3) A ̊ for SrLaZn_0.5Mn_0.5O₄. Comparing lengths of (MnO) bonds calculated with space group P422, the local symmetry of (MnO₆) octahedron is strongly dependent on competing Mg and Zn ions in the perovskite-type plane.
