Materials Data on Mg2Cd by Materials Project

Abstract

Mg2Cd crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Mg is bonded to seven equivalent Mg and five equivalent Cd atoms to form distorted MgMg7Cd5 cuboctahedra that share corners with six equivalent CdMg10Cd2 cuboctahedra, corners with twelve equivalent MgMg7Cd5 cuboctahedra, edges with four equivalent CdMg10Cd2 cuboctahedra, edges with fourteen equivalent MgMg7Cd5 cuboctahedra, faces with eight equivalent CdMg10Cd2 cuboctahedra, and faces with twelve equivalent MgMg7Cd5 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.09–3.22 Å. There are a spread of Mg–Cd bond distances ranging from 3.09–3.19 Å. Cd is bonded to ten equivalent Mg and two equivalent Cd atoms to form distorted CdMg10Cd2 cuboctahedra that share corners with six equivalent CdMg10Cd2 cuboctahedra, corners with twelve equivalent MgMg7Cd5 cuboctahedra, edges with eight equivalent MgMg7Cd5 cuboctahedra, edges with ten equivalent CdMg10Cd2 cuboctahedra, faces with four equivalent CdMg10Cd2 cuboctahedra, and faces with sixteen equivalent MgMg7Cd5 cuboctahedra. Both Cd–Cd bond lengths are 3.23 Å.
