The material structure described by Sm4Bi3 crystallizes in the cubic I-43d space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Bi(1) atoms. Bi(1) is bonded to eight equivalent Sm(1) atoms to form a mixture of distorted edge, face, and corner-sharing BiSm8 hexagonal bipyramids. is represented by the CIF card [CIF]
