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.
Sm4Bi3 crystallizes in the cubic I-43d space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Bi(1) atoms. There are three shorter (3.19 Å) and three longer (3.43 Å) Sm(1)-Bi(1) bond lengths. Bi(1) is bonded to eight equivalent Sm(1) atoms to form a mixture of distorted edge, face, and corner-sharing BiSm8 hexagonal bipyramids.
