Title: Materials Data on MgCd2 by Materials Project

Abstract

MgCd2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Mg is bonded to six equivalent Mg and six Cd atoms to form distorted MgMg6Cd6 cuboctahedra that share corners with six equivalent MgMg6Cd6 cuboctahedra, corners with twelve CdMg4Cd8 cuboctahedra, edges with four equivalent MgMg6Cd6 cuboctahedra, edges with fourteen CdMg4Cd8 cuboctahedra, faces with eight equivalent MgMg6Cd6 cuboctahedra, and faces with twelve CdMg4Cd8 cuboctahedra. There are four shorter (3.19 Å) and two longer (3.22 Å) Mg–Mg bond lengths. There are a spread of Mg–Cd bond distances ranging from 3.08–3.11 Å. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded to four equivalent Mg and eight Cd atoms to form distorted CdMg4Cd8 cuboctahedra that share corners with six equivalent MgMg6Cd6 cuboctahedra, corners with twelve CdMg4Cd8 cuboctahedra, edges with three equivalent MgMg6Cd6 cuboctahedra, edges with fifteen CdMg4Cd8 cuboctahedra, faces with eight equivalent MgMg6Cd6 cuboctahedra, and faces with twelve CdMg4Cd8 cuboctahedra. There are a spread of Cd–Cd bond distances ranging from 3.17–3.22 Å. In the second Cd site, Cd is bonded to two equivalent Mg and ten Cd atoms to form distorted CdMg2Cd10 cuboctahedra that share corners with six equivalent MgMg6Cd6 cuboctahedra, corners with twelve CdMg4Cd8 cuboctahedra, edgesmore » with seven equivalent CdMg4Cd8 cuboctahedra, edges with eleven equivalent MgMg6Cd6 cuboctahedra, faces with four equivalent MgMg6Cd6 cuboctahedra, and faces with sixteen CdMg4Cd8 cuboctahedra. There are two shorter (3.13 Å) and two longer (3.22 Å) Cd–Cd bond lengths.« less
