Abstract
Mg14CeFe crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are ten inequivalent Mg sites. In the first Mg site, Mg is bonded to ten Mg and two equivalent Fe atoms to form distorted MgMg10Fe2 cuboctahedra that share corners with four equivalent CeMg12 cuboctahedra, corners with fourteen MgMg10Fe2 cuboctahedra, edges with two equivalent FeMg12 cuboctahedra, edges with eight MgMg10Fe2 cuboctahedra, faces with two equivalent FeMg12 cuboctahedra, and faces with eight MgCe2Mg10 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.03–3.31 Å. Both Mg–Fe bond lengths are 3.21 Å. In the second Mg site, Mg is bonded to ten Mg and two equivalent Ce atoms to form distorted MgCe2Mg10 cuboctahedra that share corners with four equivalent FeMg12 cuboctahedra, corners with fourteen MgCe2Mg10 cuboctahedra, edges with two equivalent CeMg12 cuboctahedra, edges with eight MgCe2Mg10 cuboctahedra, faces with two equivalent CeMg12 cuboctahedra, and faces with eight MgMg10Fe2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.07–3.38 Å. Both Mg–Ce bond lengths are 3.21 Å. In the third Mg site, Mg is bonded to ten Mg and two equivalent Fe atoms to form distorted MgMg10Fe2 cuboctahedra that share corners with four equivalent CeMg12 cuboctahedra, cornersmore »
