Abstract

Mg6CeZn 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 in a 12-coordinate geometry to eight Mg, two equivalent Ce, and two equivalent Zn atoms. There are a spread of Mg–Mg bond distances ranging from 3.15–3.29 Å. There are one shorter (3.32 Å) and one longer (3.35 Å) Mg–Ce bond lengths. There are one shorter (3.24 Å) and one longer (3.44 Å) Mg–Zn bond lengths. In the second Mg site, Mg is bonded in a 12-coordinate geometry to eight Mg, two equivalent Ce, and two equivalent Zn atoms. There are a spread of Mg–Mg bond distances ranging from 3.08–3.44 Å. Both Mg–Ce bond lengths are 3.23 Å. Both Mg–Zn bond lengths are 3.13 Å. In the third Mg site, Mg is bonded to ten Mg and two equivalent Zn atoms to form distorted MgMg10Zn2 cuboctahedra that share corners with ten MgMg10Zn2 cuboctahedra, edges with two equivalent MgCe2Mg10 cuboctahedra, faces with four MgMg10Zn2 cuboctahedra, and faces with six equivalent CeMg10Zn2 cuboctahedra. Both Mg–Mg bond lengths are 3.23 Å. Both Mg–Zn bond lengths are 3.23 Å. In the fourth Mg site, Mg is bonded to tenmore »« less
