摘要：

Structure refinements from powder diffraction data are presented for two compounds of this type, Ca2Fe1.4Mg0.3Si0.3O5 and Ca2Fe1.07Al0.67Mg0.13Si0.13O5. Although site occupancies have not been successfully determined for the latter, results confirm the anion-deficient perovskite structure for both compounds.
