Materials Data on NdCd2 by Materials Project

Abstract

NdCd2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Nd is bonded to two equivalent Nd and six equivalent Cd atoms to form distorted NdNd2Cd6 hexagonal bipyramids that share corners with two equivalent NdNd2Cd6 hexagonal bipyramids, corners with six equivalent CdNd3Cd5 hexagonal bipyramids, edges with six equivalent NdNd2Cd6 hexagonal bipyramids, and edges with eighteen equivalent CdNd3Cd5 hexagonal bipyramids. Both Nd–Nd bond lengths are 3.42 Å. There are four shorter (3.19 Å) and two longer (3.20 Å) Nd–Cd bond lengths. Cd is bonded to three equivalent Nd and five equivalent Cd atoms to form distorted CdNd3Cd5 hexagonal bipyramids that share corners with three equivalent NdNd2Cd6 hexagonal bipyramids, corners with five equivalent CdNd3Cd5 hexagonal bipyramids, edges with nine equivalent NdNd2Cd6 hexagonal bipyramids, and edges with fifteen equivalent CdNd3Cd5 hexagonal bipyramids. There are a spread of Cd–Cd bond distances ranging from 3.20–3.42 Å.
