Abstract

MgCd2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Mg is bonded to four equivalent Mg and eight Cd atoms to form distorted MgMg4Cd8 cuboctahedra that share corners with six equivalent MgMg4Cd8 cuboctahedra, corners with twelve CdMg6Cd6 cuboctahedra, edges with eighteen CdMg6Cd6 cuboctahedra, faces with ten equivalent MgMg4Cd8 cuboctahedra, and faces with ten CdMg6Cd6 cuboctahedra. There are two shorter (3.16 Å) and two longer (3.22 Å) Mg–Mg bond lengths. There are two shorter (3.10 Å) and six longer (3.13 Å) Mg–Cd bond lengths. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded to six equivalent Mg and six Cd atoms to form distorted CdMg6Cd6 cuboctahedra that share corners with six equivalent MgMg4Cd8 cuboctahedra, corners with twelve CdMg6Cd6 cuboctahedra, edges with seven equivalent MgMg4Cd8 cuboctahedra, edges with eleven CdMg6Cd6 cuboctahedra, faces with six equivalent MgMg4Cd8 cuboctahedra, and faces with fourteen CdMg6Cd6 cuboctahedra. There are a spread of Cd–Cd bond distances ranging from 3.14–3.22 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 MgMg4Cd8 cuboctahedra, corners with twelve CdMg6Cd6 cuboctahedra, edges with seven CdMg6Cd6 cuboctahedra,more »« less
