Materials Data on Ba(FeO2)4 by Materials Project
Ba(FeO2)4 crystallizes in the trigonal P-31m space group. The structure is two-dimensional and consists of one Ba(FeO2)4 sheet oriented in the (0, 0, 1) direction. Ba is bonded to twelve O atoms to form BaO12 cuboctahedra that share edges with six equivalent BaO12 cuboctahedra and edges with twelve equivalent FeO4 tetrahedra. There are six shorter (2.98 Å) and six longer (3.25 Å) Ba–O bond lengths. Fe is bonded to four O atoms to form FeO4 tetrahedra that share corners with four equivalent FeO4 tetrahedra and edges with three equivalent BaO12 cuboctahedra. There is three shorter (1.86 Å) and one longer (1.87 Å) Fe–O bond length. There are two inequivalent O sites. In the first O site, O is bonded in a linear geometry to three equivalent Ba and two equivalent Fe atoms. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one Ba and two equivalent Fe atoms.
