The material described by CeOs4As12 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 Os(1)As6 octahedra. Os(1) is bonded to six equivalent As(1) atoms to form OsAs6 octahedra that share corners with six equivalent Os(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 Os(1), and two equivalent As(1) atoms. is represented by the CIF file [CIF]
