Materials Data on LaSb2Au by Materials Project

Abstract

LaAuSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. La3+ is bonded in a distorted hexagonal planar geometry to six Sb3- atoms. There are a spread of La–Sb bond distances ranging from 3.24–3.27 Å. Au3+ is bonded in a distorted hexagonal planar geometry to six Sb3- atoms. There are four shorter (3.24 Å) and two longer (3.25 Å) Au–Sb bond lengths. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 6-coordinate geometry to two equivalent La3+ and four equivalent Au3+ atoms. In the second Sb3- site, Sb3- is bonded in a 6-coordinate geometry to four equivalent La3+ and two equivalent Au3+ atoms.
