The compound described by Ce2Sn5 crystallizes in the monoclinic P2/m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Sn(1), two equivalent Sn(2), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(5) atoms to form a mixture of corner and face-sharing CeSn12 cuboctahedra. In the second Ce site, Ce(2) is bonded in a 10-coordinate geometry to two equivalent Sn(3), two equivalent Sn(4), and six equivalent Sn(6) atoms. There are six inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted square co-planar geometry to four equivalent Ce(1) atoms. In the second Sn site, Sn(2) is bonded in a distorted square co-planar geometry to four equivalent Ce(1) atoms. In the third Sn site, Sn(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ce(1), two equivalent Ce(2), and four equivalent Sn(4) atoms. In the fourth Sn site, Sn(4) is bonded in a 10-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Sn(5), and four equivalent Sn(3) atoms. In the fifth Sn site, Sn(5) is bonded in a distorted square co-planar geometry to four equivalent Ce(1) and two equivalent Sn(4) atoms. In the sixth Sn site, Sn(6) is bonded in a 8-coordinate geometry to six equivalent Ce(2) and two equivalent Sn(6) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
