Abstract

Mg6GaSb crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded to eight Mg, two equivalent Ga, and two equivalent Sb atoms to form a mixture of distorted face, edge, and corner-sharing MgMg8Ga2Sb2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.07–3.25 Å. There are one shorter (3.04 Å) and one longer (3.27 Å) Mg–Ga bond lengths. Both Mg–Sb bond lengths are 3.16 Å. In the second Mg site, Mg is bonded to ten Mg and two equivalent Ga atoms to form a mixture of distorted face, edge, and corner-sharing MgMg10Ga2 cuboctahedra. There are four shorter (3.19 Å) and two longer (3.20 Å) Mg–Mg bond lengths. Both Mg–Ga bond lengths are 3.08 Å. In the third Mg site, Mg is bonded to eight Mg, two equivalent Ga, and two equivalent Sb atoms to form a mixture of distorted face, edge, and corner-sharing MgMg8Ga2Sb2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.03–3.20 Å. Both Mg–Ga bond lengths are 3.12 Å. There are one shorter (3.15 Å) and one longer (3.16 Å) Mg–Sb bond lengths.
