Materials Data on V2Cd3(GeO4)3 by Materials Project

V2Cd3(GeO4)3 crystallizes in the cubic Ia-3d space group. The structure is three-dimensional. V3+ is bonded to six equivalent O2- atoms to form VO6 octahedra that share corners with six equivalent GeO4 tetrahedra. All V–O bond lengths are 2.04 Å. Cd2+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.40 Å) and four longer (2.58 Å) Cd–O bond lengths. Ge4+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent VO6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Ge–O bond lengths are 1.79 Å. O2- is bonded in a 4-coordinate geometry to one V3+, two equivalent Cd2+, and one Ge4+ atom.
