Materials Data on LiMg5 by Materials Project
Abstract
LiMg5 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Li is bonded to two equivalent Li and ten Mg atoms to form distorted LiLi2Mg10 cuboctahedra that share corners with six equivalent LiLi2Mg10 cuboctahedra, corners with twelve MgLi2Mg10 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, faces with four equivalent LiLi2Mg10 cuboctahedra, and faces with sixteen MgMg12 cuboctahedra. Both Li–Li bond lengths are 3.17 Å. There are a spread of Li–Mg bond distances ranging from 3.14–3.16 Å. 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 LiLi2Mg10 cuboctahedra, edges with ten MgLi4Mg8 cuboctahedra, faces with two equivalent LiLi2Mg10 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.15–3.19 Å. In the second Mg site, Mg is bonded to four equivalent Li and eight Mg atoms to form distorted MgLi4Mg8 cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with four equivalent LiLi2Mg10 cuboctahedra, edges with fourteen MgMg12 cuboctahedra, faces with four equivalent LiLi2Mg10 cuboctahedra, and faces with sixteen MgMg12 cuboctahedra. There are four shorter (3.15 Å) and twomore »
