PtIn6Ge2O9 is Ilmenite-derived structured and crystallizes in the cubic Fm-3m space group. Pt(1) is bonded to six equivalent In(1) atoms to form PtIn6 octahedra that share corners with six equivalent O(1)In6 octahedra. The corner-sharing octahedra are not tilted. In(1) is bonded in a 6-coordinate geometry to one Pt(1), one O(1), and four equivalent O(2) atoms. Ge(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to six equivalent In(1) atoms to form OIn6 octahedra that share corners with six equivalent Pt(1)In6 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent In(1) and one Ge(1) atom.
