Materials Data on Ge3(SbO3)4 by Materials Project
Sb4Ge3O12 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Ge4+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Ge–O bond lengths are 1.77 Å. Sb3+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are three shorter (2.04 Å) and three longer (2.74 Å) Sb–O bond lengths. O2- is bonded in a 2-coordinate geometry to one Ge4+ and two equivalent Sb3+ atoms.
