Materials Data on Ce2Bi by Materials Project
Ce2Bi crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Bi atoms. All Ce–Ce bond lengths are 3.22 Å. All Ce–Bi bond lengths are 3.37 Å. In the second Ce site, Ce is bonded to five equivalent Bi atoms to form a mixture of distorted edge and corner-sharing CeBi5 square pyramids. There are four shorter (3.28 Å) and one longer (3.36 Å) Ce–Bi bond lengths. Bi is bonded in a 9-coordinate geometry to nine Ce atoms.
