Materials Data on CeMg14Cd by Materials Project
Abstract
Mg14CeCd 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 CdCe2Mg10 cuboctahedra, corners with fourteen MgMg12 cuboctahedra, edges with eighteen MgCeMg10Cd cuboctahedra, faces with two equivalent CeMg10Cd2 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.16–3.24 Å. In the second Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with four equivalent CeMg10Cd2 cuboctahedra, corners with fourteen MgMg12 cuboctahedra, edges with eighteen MgCeMg10Cd cuboctahedra, faces with two equivalent CdCe2Mg10 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.15–3.24 Å. In the third Mg site, Mg is bonded to eight Mg, two equivalent Ce, and two equivalent Cd atoms to form distorted MgCe2Mg8Cd2 cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with two equivalent CeMg10Cd2 cuboctahedra, edges with two equivalent CdCe2Mg10 cuboctahedra, edges with fourteen MgCe2Mg8Cd2 cuboctahedra, faces with two equivalent CeMg10Cd2 cuboctahedra, faces with two equivalent CdCe2Mg10 cuboctahedra, and faces with sixteen MgCe2Mg8Cd2 cuboctahedra.more »
