Materials Data on YbCd2 by Materials Project
YbCd2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded in a 12-coordinate geometry to twelve Cd atoms. There are a spread of Yb–Cd bond distances ranging from 3.48–3.53 Å. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded to six equivalent Yb and six equivalent Cd atoms to form a mixture of edge, face, and corner-sharing CdYb6Cd6 cuboctahedra. All Cd–Cd bond lengths are 3.05 Å. In the second Cd site, Cd is bonded to six equivalent Yb and six Cd atoms to form a mixture of edge, face, and corner-sharing CdYb6Cd6 cuboctahedra. There are two shorter (2.91 Å) and two longer (3.04 Å) Cd–Cd bond lengths.
