Materials Data on Ho2CdCu2 by Materials Project
Ho2Cu2Cd crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Ho is bonded in a 6-coordinate geometry to six equivalent Cu and four equivalent Cd atoms. There are two shorter (2.86 Å) and four longer (2.91 Å) Ho–Cu bond lengths. All Ho–Cd bond lengths are 3.33 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Ho, one Cu, and two equivalent Cd atoms. The Cu–Cu bond length is 2.51 Å. Both Cu–Cd bond lengths are 3.04 Å. Cd is bonded to eight equivalent Ho and four equivalent Cu atoms to form a mixture of corner and face-sharing CdHo8Cu4 cuboctahedra.
