Abstract

Mg7Y crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. there are three 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 four equivalent YMg12 cuboctahedra, corners with fourteen equivalent MgY2Mg10 cuboctahedra, edges with two equivalent YMg12 cuboctahedra, edges with sixteen MgY2Mg10 cuboctahedra, faces with two equivalent YMg12 cuboctahedra, and faces with eighteen MgY2Mg10 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.20–3.36 Å. Both Mg–Y bond lengths are 3.31 Å. In the second 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 four equivalent YMg12 cuboctahedra, edges with fourteen MgY2Mg10 cuboctahedra, faces with two equivalent YMg12 cuboctahedra, and faces with eighteen MgY2Mg10 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.27–3.35 Å. Both Mg–Y bond lengths are 3.23 Å. In the third Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with eighteen MgY2Mg10 cuboctahedra, edges with eighteen MgY2Mg10 cuboctahedra, faces with six equivalent YMg12 cuboctahedra, and faces withmore »« less
