Materials Data on Tb2CdCu2 by Materials Project

Tb2Cu2Cd crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Tb is bonded in a 6-coordinate geometry to six equivalent Cu and four equivalent Cd atoms. There are two shorter (2.88 Å) and four longer (2.93 Å) Tb–Cu bond lengths. All Tb–Cd bond lengths are 3.36 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Tb, one Cu, and two equivalent Cd atoms. The Cu–Cu bond length is 2.53 Å. Both Cu–Cd bond lengths are 3.07 Å. Cd is bonded to eight equivalent Tb and four equivalent Cu atoms to form a mixture of face and corner-sharing CdTb8Cu4 cuboctahedra.
