Li4Be3As3O12Cl crystallizes in the cubic P-43n space group. Li(1) is bonded to three equivalent O(1) and one Cl(1) atom to form LiClO3 tetrahedra that share corners with three equivalent Li(1)ClO3 tetrahedra, corners with three equivalent Be(1)O4 tetrahedra, and corners with three equivalent As(1)O4 tetrahedra. Be(1) is bonded to four equivalent O(1) atoms to form BeO4 tetrahedra that share corners with four equivalent Li(1)ClO3 tetrahedra and corners with four equivalent As(1)O4 tetrahedra. As(1) is bonded to four equivalent O(1) atoms to form AsO4 tetrahedra that share corners with four equivalent Li(1)ClO3 tetrahedra and corners with four equivalent Be(1)O4 tetrahedra. O(1) is bonded in a trigonal planar geometry to one Li(1), one Be(1), and one As(1) atom. Cl(1) is bonded in a tetrahedral geometry to four equivalent Li(1) atoms.
