Materials Data on Tb4Bi3 by Materials Project
Tb4Bi3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Tb is bonded to six equivalent Bi atoms to form a mixture of distorted edge, corner, and face-sharing TbBi6 octahedra. The corner-sharing octahedra tilt angles range from 18–49°. There are three shorter (3.17 Å) and three longer (3.37 Å) Tb–Bi bond lengths. Bi is bonded to eight equivalent Tb atoms to form a mixture of distorted edge, corner, and face-sharing BiTb8 hexagonal bipyramids.
