Materials Data on Tb3Se4 by Materials Project
Tb3Se4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Tb is bonded to eight equivalent Se atoms to form a mixture of distorted edge, corner, and face-sharing TbSe8 hexagonal bipyramids. There are four shorter (2.92 Å) and four longer (3.13 Å) Tb–Se bond lengths. Se is bonded to six equivalent Tb atoms to form a mixture of distorted edge, corner, and face-sharing SeTb6 octahedra. The corner-sharing octahedra tilt angles range from 18–49°.
