Title: Materials Data on SmAl3Cu by Materials Project

Abstract

SmCuAl3 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Sm is bonded in a 8-coordinate geometry to four equivalent Cu and twelve Al atoms. All Sm–Cu bond lengths are 3.26 Å. There are a spread of Sm–Al bond distances ranging from 3.12–3.39 Å. Cu is bonded in a 5-coordinate geometry to four equivalent Sm and five Al atoms. There are one shorter (2.35 Å) and four longer (2.45 Å) Cu–Al bond lengths. There are two inequivalent Al sites. In the first Al site, Al is bonded in a distorted bent 120 degrees geometry to four equivalent Sm and two equivalent Cu atoms. In the second Al site, Al is bonded in a distorted single-bond geometry to four equivalent Sm and one Cu atom.
