Materials Data on NdCd2 by Materials Project

NdCd2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Nd is bonded to two equivalent Nd and twelve equivalent Cd atoms to form a mixture of distorted corner, edge, and face-sharing NdNd2Cd12 cuboctahedra. Both Nd–Nd bond lengths are 3.45 Å. There are six shorter (3.41 Å) and six longer (3.43 Å) Nd–Cd bond lengths. Cd is bonded in a 11-coordinate geometry to six equivalent Nd and five equivalent Cd atoms. There are three shorter (2.95 Å) and two longer (3.45 Å) Cd–Cd bond lengths.

Materials Data on NdCd3 by Materials Project

NdCd3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Nd is bonded in a distorted body-centered cubic geometry to fourteen Cd atoms. There are eight shorter (3.17 Å) and six longer (3.66 Å) Nd–Cd bond lengths. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded in a distorted body-centered cubic geometry to four equivalent Nd and four equivalent Cd atoms. All Cd–Cd bond lengths are 3.17 Å. In the second Cd site, Cd is bonded in a 8-coordinate geometry to six equivalent Nd and eight equivalent Cd atoms.
