The structure described by CeZn11 crystallizes in the tetragonal I4_1/amd space group. Ce(1) is bonded in a 18-coordinate geometry to two equivalent Zn(3) and sixteen equivalent Zn(1) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(3) is bonded in a 14-coordinate geometry to two equivalent Ce(1), four equivalent Zn(2), and eight equivalent Zn(1) atoms. In the second Zn site, Zn(1) is bonded to two equivalent Ce(1), one Zn(3), two equivalent Zn(2), and seven equivalent Zn(1) atoms to form a mixture of distorted corner, edge, and face-sharing ZnCe2Zn10 cuboctahedra. In the third Zn site, Zn(2) is bonded in a 10-coordinate geometry to two equivalent Zn(3) and eight equivalent Zn(1) atoms. is represented by the CIF file [CIF]
