The structure described by Ce4Bi3 crystallizes in the cubic I-43d space group. Ce(1) is bonded to six equivalent Bi(1) atoms to form a mixture of distorted edge, face, and corner-sharing CeBi6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°. Bi(1) is bonded to eight equivalent Ce(1) atoms to form a mixture of distorted edge, face, and corner-sharing BiCe8 hexagonal bipyramids. is represented by the CIF card [CIF]
