The structure described by Na4Al3Ge3O12I crystallizes in the cubic P-43n space group. Na(1) is bonded to three equivalent O(1) and one I(1) atom to form distorted NaIO3 tetrahedra that share corners with three equivalent Na(1)IO3 tetrahedra, corners with three equivalent Al(1)O4 tetrahedra, and corners with three equivalent Ge(1)O4 tetrahedra. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Na(1)IO3 tetrahedra and corners with four equivalent Ge(1)O4 tetrahedra. Ge(1) is bonded to four equivalent O(1) atoms to form GeO4 tetrahedra that share corners with four equivalent Na(1)IO3 tetrahedra and corners with four equivalent Al(1)O4 tetrahedra. O(1) is bonded in a distorted trigonal planar geometry to one Na(1), one Al(1), and one Ge(1) atom. I(1) is bonded in a tetrahedral geometry to four equivalent Na(1) atoms. is represented by the CIF file [CIF]
