Materials Data on TmMg5 by Materials Project
Abstract
Mg5Tm is Magnesium-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are five inequivalent Mg sites. In the first Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with eight equivalent TmTm2Mg10 cuboctahedra, edges with ten MgTm4Mg8 cuboctahedra, faces with two equivalent TmTm2Mg10 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.20–3.27 Å. In the second Mg site, Mg is bonded to eight Mg and four equivalent Tm atoms to form MgTm4Mg8 cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with four equivalent TmTm2Mg10 cuboctahedra, edges with fourteen MgMg12 cuboctahedra, faces with four equivalent TmTm2Mg10 cuboctahedra, and faces with sixteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.22–3.34 Å. All Mg–Tm bond lengths are 3.27 Å. In the third Mg site, Mg is bonded to ten Mg and two equivalent Tm atoms to form MgTm2Mg10 cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, faces with six equivalent TmTm2Mg10 cuboctahedra, and faces with fourteen MgMg12 cuboctahedra. There are two shorter (3.22 Å) andmore »
