Abstract
MgY crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded in a 10-coordinate geometry to six Mg and four Y atoms. There are two shorter (3.32 Å) and four longer (3.38 Å) Mg–Mg bond lengths. There are two shorter (3.26 Å) and two longer (3.32 Å) Mg–Y bond lengths. In the second Mg site, Mg is bonded in a 10-coordinate geometry to four Mg and six Y atoms. Both Mg–Mg bond lengths are 3.29 Å. There are four shorter (3.37 Å) and two longer (3.42 Å) Mg–Y bond lengths. In the third Mg site, Mg is bonded in a 10-coordinate geometry to six Mg and four Y atoms. There are two shorter (3.34 Å) and two longer (3.46 Å) Mg–Y bond lengths. There are three inequivalent Y sites. In the first Y site, Y is bonded to six Mg and six Y atoms to form distorted YY6Mg6 cuboctahedra that share corners with twelve YY6Mg6 cuboctahedra, edges with three equivalent YY8Mg4 cuboctahedra, and faces with twelve YY6Mg6 cuboctahedra. There are a spread of Y–Y bond distances ranging from 3.44–3.61 Å. In the second Y site,more »
