CeRu4As12 crystallizes in the cubic Im-3 space group. Ce(1) is bonded to twelve equivalent As(1) atoms to form CeAs12 cuboctahedra that share faces with eight equivalent Ru(1)As6 octahedra. Ru(1) is bonded to six equivalent As(1) atoms to form RuAs6 octahedra that share corners with six equivalent Ru(1)As6 octahedra and faces with two equivalent Ce(1)As12 cuboctahedra. The corner-sharing octahedral tilt angles are 59°. As(1) is bonded in a 5-coordinate geometry to one Ce(1), two equivalent Ru(1), and two equivalent As(1) atoms.
CeRu4As12 crystallizes in the cubic Im-3 space group. Ce(1) is bonded to twelve equivalent As(1) atoms to form CeAs12 cuboctahedra that share faces with eight equivalent Ru(1)As6 octahedra. All Ce(1)-As(1) bond lengths are 3.24 Å. Ru(1) is bonded to six equivalent As(1) atoms to form RuAs6 octahedra that share corners with six equivalent Ru(1)As6 octahedra and faces with two equivalent Ce(1)As12 cuboctahedra.
