Title: Materials Data on Sm4MgRh by Materials Project

Abstract

MgSm4Rh crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mg is bonded to three equivalent Mg and nine Sm atoms to form a mixture of corner and face-sharing MgSm9Mg3 cuboctahedra. All Mg–Mg bond lengths are 3.14 Å. There are a spread of Mg–Sm bond distances ranging from 3.39–3.62 Å. There are three inequivalent Sm sites. In the first Sm site, Sm is bonded in a 4-coordinate geometry to two equivalent Mg, ten Sm, and two equivalent Rh atoms. There are a spread of Sm–Sm bond distances ranging from 3.60–3.72 Å. Both Sm–Rh bond lengths are 3.59 Å. In the second Sm site, Sm is bonded in a bent 150 degrees geometry to two equivalent Mg, four equivalent Sm, and two equivalent Rh atoms. Both Sm–Rh bond lengths are 2.88 Å. In the third Sm site, Sm is bonded in a 3-coordinate geometry to three equivalent Mg, three equivalent Sm, and three equivalent Rh atoms. All Sm–Rh bond lengths are 2.88 Å. Rh is bonded in a 6-coordinate geometry to nine Sm atoms.
