Materials Data on Ce4Bi3 by Materials Project

Ce4Bi3 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Ce is bonded to six equivalent Bi atoms to form a mixture of distorted edge, corner, and face-sharing CeBi6 octahedra. The corner-sharing octahedra tilt angles range from 17–50°. There are three shorter (3.27 Å) and three longer (3.46 Å) Ce–Bi bond lengths. Bi is bonded to eight equivalent Ce atoms to form a mixture of distorted edge, corner, and face-sharing BiCe8 hexagonal bipyramids.
