Materials Data on Sm2Mg by Materials Project
MgSm2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Mg is bonded in a body-centered cubic geometry to eight Sm atoms. There are a spread of Mg–Sm bond distances ranging from 3.33–3.39 Å. There are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 12-coordinate geometry to six equivalent Mg and four equivalent Sm atoms. There are two shorter (3.68 Å) and two longer (3.69 Å) Sm–Sm bond lengths. In the second Sm site, Sm is bonded in a 12-coordinate geometry to two equivalent Mg and ten Sm atoms. There are four shorter (3.46 Å) and two longer (3.77 Å) Sm–Sm bond lengths.
