Title: Materials Data on YMg2 by Materials Project

Abstract

Mg2Y is beta-derived structured and 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 to ten Mg and two equivalent Y atoms to form MgY2Mg10 cuboctahedra that share corners with eighteen MgY2Mg10 cuboctahedra, edges with eight equivalent YY4Mg8 cuboctahedra, edges with ten MgY4Mg8 cuboctahedra, faces with eight YY4Mg8 cuboctahedra, and faces with twelve MgY2Mg10 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.33–3.44 Å. Both Mg–Y bond lengths are 3.34 Å. In the second Mg site, Mg is bonded to eight Mg and four equivalent Y atoms to form MgY4Mg8 cuboctahedra that share corners with eighteen MgY2Mg10 cuboctahedra, edges with six MgY2Mg10 cuboctahedra, edges with twelve YY4Mg8 cuboctahedra, faces with six YY4Mg8 cuboctahedra, and faces with fourteen MgY2Mg10 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.33–3.38 Å. All Mg–Y bond lengths are 3.33 Å. In the third Mg site, Mg is bonded to six Mg and six Y atoms to form MgY6Mg6 cuboctahedra that share corners with eighteen MgY2Mg10 cuboctahedra, edges with four equivalent YY4Mg8 cuboctahedra, edges with fourteen MgY2Mg10 cuboctahedra, faces with ten MgY2Mg10 cuboctahedra, andmore » faces with ten YY4Mg8 cuboctahedra. Both Mg–Mg bond lengths are 3.38 Å. All Mg–Y bond lengths are 3.38 Å. In the fourth Mg site, Mg is bonded to eight Mg and four Y atoms to form MgY4Mg8 cuboctahedra that share corners with six equivalent MgY4Mg8 cuboctahedra, corners with twelve YY4Mg8 cuboctahedra, edges with six YY4Mg8 cuboctahedra, edges with twelve MgY2Mg10 cuboctahedra, faces with four YY4Mg8 cuboctahedra, and faces with sixteen MgY2Mg10 cuboctahedra. Both Mg–Mg bond lengths are 3.38 Å. There are two shorter (3.28 Å) and two longer (3.33 Å) Mg–Y bond lengths. There are two inequivalent Y sites. In the first Y site, Y is bonded to eight Mg and four Y atoms to form YY4Mg8 cuboctahedra that share corners with six equivalent MgY4Mg8 cuboctahedra, corners with twelve YY4Mg8 cuboctahedra, edges with three equivalent YY4Mg8 cuboctahedra, edges with fifteen MgY2Mg10 cuboctahedra, faces with six YY4Mg8 cuboctahedra, and faces with fourteen MgY2Mg10 cuboctahedra. There are two shorter (3.38 Å) and two longer (3.50 Å) Y–Y bond lengths. In the second Y site, Y is bonded to eight Mg and four Y atoms to form YY4Mg8 cuboctahedra that share corners with six equivalent MgY4Mg8 cuboctahedra, corners with twelve YY4Mg8 cuboctahedra, edges with three equivalent YY4Mg8 cuboctahedra, edges with fifteen MgY4Mg8 cuboctahedra, faces with six YY4Mg8 cuboctahedra, and faces with fourteen MgY2Mg10 cuboctahedra. Both Y–Y bond lengths are 3.38 Å.« less
