Abstract

Mg14CeFe crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are seven inequivalent Mg sites. In the first Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with four equivalent CeMg10Fe2 cuboctahedra, corners with six equivalent MgMg12 cuboctahedra, edges with two equivalent MgMg12 cuboctahedra, and faces with two equivalent MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 2.96–3.39 Å. In the second Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with six equivalent MgMg12 cuboctahedra, edges with two equivalent MgMg12 cuboctahedra, faces with two equivalent MgMg12 cuboctahedra, and faces with two equivalent CeMg10Fe2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.07–3.32 Å. In the third Mg site, Mg is bonded in a 1-coordinate geometry to four Mg, two equivalent Ce, and one Fe atom. There are two shorter (3.02 Å) and two longer (3.38 Å) Mg–Mg bond lengths. There are one shorter (3.24 Å) and one longer (3.27 Å) Mg–Ce bond lengths. The Mg–Fe bond length is 2.92 Å. In the fourth Mg site, Mg is bonded in a 10-coordinate geometry to ten Mgmore »« less
