Materials Data on Sm2NiSn4 by Materials Project
Sm2NiSn4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 12-coordinate geometry to three equivalent Ni and ten Sn atoms. There are two shorter (3.52 Å) and one longer (3.59 Å) Sm–Ni bond lengths. There are a spread of Sm–Sn bond distances ranging from 3.28–3.71 Å. In the second Sm site, Sm is bonded in a 12-coordinate geometry to two equivalent Ni and ten Sn atoms. Both Sm–Ni bond lengths are 3.36 Å. There are a spread of Sm–Sn bond distances ranging from 3.25–3.70 Å. Ni is bonded in a 10-coordinate geometry to five Sm and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.53–2.63 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to four Sm, one Ni, and four Sn atoms. There are two shorter (3.01 Å) and two longer (3.26 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a 7-coordinate geometry to four Sm, three equivalent Ni, and two equivalent Sn atoms. In the third Sn site, Sn is bonded in a 4-coordinate geometry to six Sm and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.99 Å. In the fourth Sn site, Sn is bonded in a 9-coordinate geometry to six Sm, one Ni, and two equivalent Sn atoms.
