Ce2Bi crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Bi(1) atoms. In the second Ce site, Ce(2) is bonded to five equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing CeBi5 trigonal bipyramids. Bi(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
Ce2Bi crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Bi(1) atoms. All Ce(1)-Ce(1) bond lengths are 3.26 Å. All Ce(1)-Bi(1) bond lengths are 3.42 Å. In the second Ce site, Ce(2) is bonded to five equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing CeBi5 trigonal bipyramids. There are four shorter (3.36 Å) and one longer (3.39 Å) Ce(2)-Bi(1) bond length. Bi(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
