The material structure described by Na4Ga3Si3O12Br crystallizes in the cubic P-43n space group. Na(1) is bonded to three equivalent O(1) and one Br(1) atom to form NaBrO3 tetrahedra that share corners with three equivalent Na(1)BrO3 tetrahedra, corners with three equivalent Ga(1)O4 tetrahedra, and corners with three equivalent Si(1)O4 tetrahedra. Ga(1) is bonded to four equivalent O(1) atoms to form GaO4 tetrahedra that share corners with four equivalent Na(1)BrO3 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Na(1)BrO3 tetrahedra and corners with four equivalent Ga(1)O4 tetrahedra. O(1) is bonded in a distorted trigonal planar geometry to one Na(1), one Ga(1), and one Si(1) atom. Br(1) is bonded in a tetrahedral geometry to four equivalent Na(1) atoms. is represented by the CIF card [CIF]
