Materials Data on Nd(Cd10Ni)2 by Materials Project
Nd(NiCd10)2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Nd is bonded in a 4-coordinate geometry to sixteen Cd atoms. There are four shorter (3.42 Å) and twelve longer (3.47 Å) Nd–Cd bond lengths. Ni is bonded to twelve Cd atoms to form NiCd12 cuboctahedra that share corners with six equivalent NiCd12 cuboctahedra, edges with eighteen equivalent CdNdCd10Ni cuboctahedra, and faces with six equivalent CdNdCd10Ni cuboctahedra. There are six shorter (2.80 Å) and six longer (3.08 Å) Ni–Cd bond lengths. There are three inequivalent Cd sites. In the first Cd site, Cd is bonded in a 2-coordinate geometry to two equivalent Ni and ten Cd atoms. There are a spread of Cd–Cd bond distances ranging from 2.97–3.12 Å. In the second Cd site, Cd is bonded to one Nd, one Ni, and ten Cd atoms to form distorted CdNdCd10Ni cuboctahedra that share corners with fifteen equivalent CdNdCd10Ni cuboctahedra, edges with two equivalent CdNdCd10Ni cuboctahedra, edges with three equivalent NiCd12 cuboctahedra, a faceface with one NiCd12 cuboctahedra, and faces with fifteen equivalent CdNdCd10Ni cuboctahedra. There are a spread of Cd–Cd bond distances ranging from 2.92–3.36 Å. In the third Cd site, Cd is bonded in a distorted linear geometry to two equivalent Nd and twelve equivalent Cd atoms.
