Tm2Cu2Cd crystallizes in the tetragonal P4/mbm space group. Tm(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Cd(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1), one Cu(1), and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Tm(1) and four equivalent Cu(1) atoms to form a mixture of corner and face-sharing CdTm8Cu4 cuboctahedra.
Tm2Cu2Cd crystallizes in the tetragonal P4/mbm space group. Tm(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Cd(1) atoms. There are two shorter (2.82 Å) and four longer (2.87 Å) Tm(1)-Cu(1) bond lengths. All Tm(1)-Cd(1) bond lengths are 3.28 Å. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1), one Cu(1), and two equivalent Cd(1) atoms. The Cu(1)-Cu(1) bond length is 2.51 Å. Both Cu(1)-Cd(1) bond lengths are 2.94 Å. Cd(1) is bonded to eight equivalent Tm(1) and four equivalent Cu(1) atoms to form a mixture of corner and face-sharing CdTm8Cu4 cuboctahedra.
