Materials Data on Mg3Cr2(GeO4)3 by Materials Project
Mg3Cr2(GeO4)3 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. Mg2+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.26 Å) and four longer (2.40 Å) Mg–O bond lengths. Cr3+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All Cr–O bond lengths are 2.00 Å. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 54°. All Ge–O bond lengths are 1.77 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+, one Cr3+, and one Ge4+ atom.
