The compound described by Ce2Sb crystallizes in the monoclinic C2/m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing CeSb5 trigonal bipyramids. In the second Ce site, Ce(2) is bonded in a 8-coordinate geometry to four equivalent Ce(2) and four equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Ce(2) and five equivalent Ce(1) atoms. is represented by the CIF file [CIF]
