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.
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. Both Ce(1)-Zn(3) bond lengths are 3.40 Å. There are eight shorter (3.25 Å) and eight longer (3.36 Å) Ce(1)-Zn(1) bond lengths. 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. All Zn(3)-Zn(2) bond lengths are 2.76 Å. All Zn(3)-Zn(1) bond lengths are 2.84 Å. 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. There is one shorter (2.58 Å) and one longer (2.59 Å) Zn(1)-Zn(2) bond length. There are a spread of Zn(1)-Zn(1) bond distances ranging from 2.57-2.95 Å. 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.
