Materials Data on TmCd2 by Materials Project
TmCd2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Tm is bonded to two equivalent Tm and twelve equivalent Cd atoms to form a mixture of distorted face, edge, and corner-sharing TmTm2Cd12 cuboctahedra. Both Tm–Tm bond lengths are 3.41 Å. All Tm–Cd bond lengths are 3.33 Å. Cd is bonded in a 11-coordinate geometry to six equivalent Tm and five equivalent Cd atoms. There are three shorter (2.86 Å) and two longer (3.41 Å) Cd–Cd bond lengths.
