Title: Materials Data on Ba2Nd2Fe(CoO4)3 by Materials Project

Abstract

Ba2Nd2Fe(CoO4)3 is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with four equivalent BaO12 cuboctahedra, corners with eight equivalent NdO12 cuboctahedra, faces with two equivalent NdO12 cuboctahedra, faces with four equivalent BaO12 cuboctahedra, faces with two equivalent FeO6 octahedra, and faces with six CoO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.77–2.95 Å. Nd3+ is bonded to twelve O2- atoms to form NdO12 cuboctahedra that share corners with four equivalent NdO12 cuboctahedra, corners with eight equivalent BaO12 cuboctahedra, faces with two equivalent BaO12 cuboctahedra, faces with four equivalent NdO12 cuboctahedra, faces with two equivalent FeO6 octahedra, and faces with six CoO6 octahedra.

In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ba2+, two equivalent Nd3+, one Fe3+, and one Co+3.67+ atom. In the tenth O2- site, O2- is bonded to four equivalent Ba2+, one Fe3+, and one Co+3.67+ atom to form distorted OBa4FeCo octahedra that share corners with four equivalent OBa4Co2 octahedra and edges with four OBa4FeCo octahedra. The corner-sharing octahedral tilt angles are 2°. The O–Fe bond length is 2.12 Å. In the eleventh O2- site, O2- is bonded to four equivalent Ba2+ and two Co+3.67+ atoms to form distorted OBa4Co2 octahedra that share corners with four equivalent OBa4FeCo octahedra and edges with four OBa4Co2 octahedra.
