Materials Data on Mn2FeO4 by Materials Project
Abstract
FeMn2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are two inequivalent Mn+2.50+ sites. In the first Mn+2.50+ site, Mn+2.50+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with six equivalent MnO6 octahedra and corners with six equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 57–61°. There are two shorter (2.04 Å) and two longer (2.07 Å) Mn–O bond lengths. In the second Mn+2.50+ site, Mn+2.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent MnO4 tetrahedra, edges with two equivalent MnO6 octahedra, and edges with four equivalent FeO6 octahedra. There are two shorter (1.97 Å) and four longer (2.12 Å) Mn–O bond lengths. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent MnO4 tetrahedra, edges with two equivalent FeO6 octahedra, and edges with four equivalent MnO6 octahedra. There are two shorter (2.00 Å) and four longer (2.09 Å) Fe–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Mn+2.50+ and one Fe3+ atom to form a mixture of distorted edgemore »
