Materials Data on Sm4Bi3 by Materials Project
Sm4Bi3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Sm is bonded in a 6-coordinate geometry to six equivalent Bi atoms. There are three shorter (3.20 Å) and three longer (3.43 Å) Sm–Bi bond lengths. Bi is bonded to eight equivalent Sm atoms to form a mixture of distorted edge, corner, and face-sharing BiSm8 hexagonal bipyramids.
