Title: Materials Data on La5Mg by Materials Project

Abstract

MgLa5 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Mg is bonded in a 10-coordinate geometry to ten La atoms. There are a spread of Mg–La bond distances ranging from 3.40–3.90 Å. There are five inequivalent La sites. In the first La site, La is bonded in a 12-coordinate geometry to two equivalent Mg and five La atoms. There are a spread of La–La bond distances ranging from 3.49–3.77 Å. In the second La site, La is bonded in a 12-coordinate geometry to three equivalent Mg and three La atoms. There are one shorter (3.67 Å) and two longer (3.68 Å) La–La bond lengths. In the third La site, La is bonded in a 11-coordinate geometry to two equivalent Mg and five La atoms. There are a spread of La–La bond distances ranging from 3.59–3.79 Å. In the fourth La site, La is bonded to one Mg and eleven La atoms to form LaLa11Mg cuboctahedra that share corners with six equivalent LaLa11Mg cuboctahedra, edges with six equivalent LaLa10Mg2 cuboctahedra, and faces with five LaLa11Mg cuboctahedra. There are two shorter (3.64 Å) and two longer (3.80 Å) La–La bond lengths. In the fifth La site, La is bondedmore » to two equivalent Mg and ten La atoms to form distorted LaLa10Mg2 cuboctahedra that share corners with six equivalent LaLa10Mg2 cuboctahedra, edges with six equivalent LaLa11Mg cuboctahedra, and faces with five LaLa11Mg cuboctahedra. Both La–La bond lengths are 3.80 Å.« less
