Materials Data on SmGaCo by Materials Project
SmCoGa crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 1-coordinate geometry to four Co and six Ga atoms. There are a spread of Sm–Co bond distances ranging from 2.66–3.06 Å. There are a spread of Sm–Ga bond distances ranging from 3.07–3.33 Å. In the second Sm site, Sm is bonded in a 1-coordinate geometry to four Co and six Ga atoms. There are a spread of Sm–Co bond distances ranging from 2.65–3.06 Å. There are a spread of Sm–Ga bond distances ranging from 3.07–3.33 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 9-coordinate geometry to four Sm, two equivalent Co, and three equivalent Ga atoms. Both Co–Co bond lengths are 2.48 Å. There are one shorter (2.39 Å) and two longer (2.43 Å) Co–Ga bond lengths. In the second Co site, Co is bonded in a 9-coordinate geometry to four Sm, two equivalent Co, and three equivalent Ga atoms. Both Co–Co bond lengths are 2.48 Å. There are one shorter (2.39 Å) and two longer (2.43 Å) Co–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 6-coordinate geometry to six Sm and three equivalent Co atoms. In the second Ga site, Ga is bonded in a 6-coordinate geometry to six Sm and three equivalent Co atoms.
