Materials Data on LiMg14Nb by Materials Project
Abstract
LiMg14Nb crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Li is bonded to ten Mg and two equivalent Nb atoms to form LiMg10Nb2 cuboctahedra that share corners with six equivalent LiMg10Nb2 cuboctahedra, corners with twelve MgMg12 cuboctahedra, edges with two equivalent NbLi2Mg10 cuboctahedra, edges with sixteen MgLi2Mg8Nb2 cuboctahedra, faces with two equivalent NbLi2Mg10 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Li–Mg bond distances ranging from 3.06–3.21 Å. Both Li–Nb bond lengths are 3.19 Å. There are ten inequivalent Mg sites. In the first Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with four equivalent NbLi2Mg10 cuboctahedra, corners with fourteen MgMg12 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, faces with two equivalent LiMg10Nb2 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.13–3.19 Å. In the second Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with four equivalent LiMg10Nb2 cuboctahedra, corners with fourteen MgMg12 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, faces with two equivalent NbLi2Mg10 cuboctahedra, and faces with eighteen MgMg12 cuboctahedra.
