The structure described by IrIn6Ge2O8 is Aluminum carbonitride-derived structured and crystallizes in the cubic Fm-3m space group. Ir(1) is bonded to six equivalent In(1) atoms to form IrIn6 octahedra that share corners with twenty-four equivalent O(1)In3Ge tetrahedra. In(1) is bonded in a 5-coordinate geometry to one Ir(1) and four equivalent O(1) atoms. Ge(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent In(1) and one Ge(1) atom to form distorted OIn3Ge tetrahedra that share corners with three equivalent Ir(1)In6 octahedra, corners with six equivalent O(1)In3Ge tetrahedra, and edges with three equivalent O(1)In3Ge tetrahedra. The corner-sharing octahedral tilt angles are 64°. is represented by the CIF file [CIF]
