Materials Data on Mn3Fe2(GeO4)3 by Materials Project

Mn3Fe2(GeO4)3 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Mn2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.34 Å) and four longer (2.45 Å) Mn–O bond lengths. Fe3+ is bonded to six equivalent O2- atoms to form FeO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All Fe–O bond lengths are 2.03 Å. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Ge–O bond lengths are 1.78 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Mn2+, one Fe3+, and one Ge4+ atom.
