Be3Ag4P3O12Br crystallizes in the cubic P-43n space group. Be(1) is bonded to four equivalent O(1) atoms to form BeO4 tetrahedra that share corners with four equivalent Ag(1)BrO3 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. Ag(1) is bonded to three equivalent O(1) and one Br(1) atom to form distorted AgBrO3 tetrahedra that share corners with three equivalent Be(1)O4 tetrahedra, corners with three equivalent Ag(1)BrO3 tetrahedra, and corners with three equivalent P(1)O4 tetrahedra. P(1) is bonded to four equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent Be(1)O4 tetrahedra and corners with four equivalent Ag(1)BrO3 tetrahedra. O(1) is bonded in a distorted bent 150 degrees geometry to one Be(1), one Ag(1), and one P(1) atom. Br(1) is bonded in a tetrahedral geometry to four equivalent Ag(1) atoms.
