The material described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
