IrIn7GeO8 is Aluminum carbonitride-derived structured and crystallizes in the cubic F-43m space group. Ir(1) is bonded to six equivalent In(1) atoms to form IrIn6 octahedra that share corners with twelve equivalent O(1)In3Ge tetrahedra and corners with twelve equivalent O(2)In4 tetrahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to one Ir(1), two equivalent O(1), and two equivalent O(2) atoms. In the second In site, In(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. Ge(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, 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(2)In4 tetrahedra. The corner-sharing octahedral tilt angles are 64°. In the second O site, O(2) is bonded to one In(2) and three equivalent In(1) atoms to form OIn4 tetrahedra that share corners with three equivalent Ir(1)In6 octahedra, corners with six equivalent O(2)In4 tetrahedra, and edges with three equivalent O(1)In3Ge tetrahedra. The corner-sharing octahedral tilt angles are 57°.
