Materials Data on Tb4Sb3 by Materials Project
Tb4Sb3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Tb is bonded to six equivalent Sb atoms to form a mixture of distorted edge, face, and corner-sharing TbSb6 octahedra. The corner-sharing octahedra tilt angles range from 18–49°. There are three shorter (3.09 Å) and three longer (3.30 Å) Tb–Sb bond lengths. Sb is bonded to eight equivalent Tb atoms to form a mixture of distorted edge, face, and corner-sharing SbTb8 hexagonal bipyramids.
