Title: Materials Data on SrCa7Fe2(CoO4)6 by Materials Project

Abstract

SrCa7Fe2(CoO4)6 is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Sr is bonded to twelve O atoms to form SrO12 cuboctahedra that share corners with twelve CaO12 cuboctahedra, faces with six CaO12 cuboctahedra, faces with two equivalent FeO6 octahedra, and faces with six CoO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.70–2.74 Å. There are five inequivalent Ca sites. In the first Ca site, Ca is bonded to twelve O atoms to form CaO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, corners with eight CaO12 cuboctahedra, faces with six CaO12 cuboctahedra, faces with two equivalent FeO6 octahedra, and faces with six CoO6 octahedra. There are a spread of Ca–O bond distances ranging from 2.63–2.74 Å.
