Materials Data on La2Mg by Materials Project
La2Mg crystallizes in the trigonal R32 space group. The structure is three-dimensional. Mg is bonded in a 12-coordinate geometry to nine La atoms. There are a spread of Mg–La bond distances ranging from 3.57–3.61 Å. There are two inequivalent La sites. In the first La site, La is bonded to four equivalent Mg and eight La atoms to form a mixture of edge, face, and corner-sharing LaLa8Mg4 cuboctahedra. There are a spread of La–La bond distances ranging from 3.47–3.65 Å. In the second La site, La is bonded to six equivalent Mg and six equivalent La atoms to form LaLa6Mg6 cuboctahedra that share corners with six equivalent LaLa6Mg6 cuboctahedra, edges with eighteen LaLa8Mg4 cuboctahedra, and faces with twelve equivalent LaLa8Mg4 cuboctahedra.
