In the ninth Fe2+ site, Fe2+ is bonded to four O2- atoms to form FeO4 tetrahedra that share a cornercorner with one CrO6 octahedra, a cornercorner with one FeO6 octahedra, and corners with two FeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 40–52°. There are a spread of Fe–O bond distances ranging from 1.95–2.16 Å. In the tenth Fe2+ site, Fe2+ is bonded to fou},
